Houston-based Motif Neurotech has received FDA approval to move forward with its first clinical trial for its innovative way to fight treatment-resistant depression and other mental health disorders.

The company has developed a brain-computer interface technology based on research from Rice University. The blueberry-sized, wirelessly powered implantable device known as the Digitally-programmable Over-brain Therapeutic (DOT) stimulator delivers electrical stimulation to brain circuits linked to depression. The DOT stimulator sits in the skull above the dura without touching the brain and is considered an alternative to transcranial magnetic stimulation, which requires multiple treatment sessions and can cause headaches.

“The goal for this technology is that it would be the mental health equivalent of a continuous glucose monitor for diabetes,” Jacob Robinson, a Rice University professor of electrical computer engineering and bioengineering and CEO of Motif Neurotech, said in a news release. “What has been really special for me personally on this journey is to be able to work all the way from a concept through the process of research and development funded by the federal government at Rice, and take that into a product that is going to affect people’s lives for the better.”

Eligible adults whose depression has not improved after trying multiple therapies can take part in the study. The clinical trial will be conducted in collaboration with Baylor College of Medicine, Brain Health Consultants (Houston), UT Health Houston, Massachusetts General Brigham, Emory Healthcare, University of Iowa, University of Utah Health and New York University, according to Rice.

Motif also announced that it was one of the first teams selected for ARPA-H’s EVIDENT initiative, which recently awarded up to $139.4 million to spur new, effective therapies for behavioral health. Through the initiative, Motif will collect additional data alongside its clinical trial.

“The idea with this funding is to support a number of teams who have rapid-acting interventions for a mental health condition and to collect additional data to help determine with greater precision whether a treatment is working, how it is working and which patients are benefitting most from which course of treatment,” Robinson added in the release.

Motif Neurotech was spun out of Robinson’s and Professor Kaiyuan Yang’s labs at Rice, along with collaborators and co-founders Dr. Sameer Sheth at Baylor College of Medicine and Dr. Sunil Sheth at the University of Texas Health Science Center at Houston. It was founded through the Rice Biotech Launch Pad. The company closed its Series A round with an oversubscribed $18.75 million last year.

How a Houston company is fighting anxiety, insomnia & Alzheimer’s through waveforms

mental health

A Houston-based company is taking a medicine-free approach to target brain neurologically associated with mental illness.

Nexalin Technology’s patented, FDA-cleared frequency-based waveform targets key centers of the midbrain to support the normalization of neurochemicals through a process known as Transcranial Alternating Current Stimulation (tACS). Delivered via a non-invasive device, the treatment gently stimulates the hypothalamus and midbrain, helping to “reset networks associated with symptoms” of anxiety and insomnia. Early clinical evidence suggests this approach can promote healthier brain function and improved sleep.

Through its recently appointed scientific advisory board (SAB), Nexalin also aims to target Alzheimer’s disease with a clinical development pipeline supported by published data and internal data from studies involving its proprietary DIFS technology. Nexalin’s Gen-2 SYNC and Gen-3 Halo headset delivers the DIFS, which is a waveform that can penetrate deep brain structures implicated in cognitive decline and mental illness.

The board includes experts in neurology, neuroimaging and neurodegenerative diseases with Dr. Mingxiong Huang, Dr. David Owens, and Dr. Abe Scheer coming on board. Nexalin plans to initiate new Alzheimer’s-focused clinical studies in the Q3 2025 by incorporating cognitive testing, imaging biomarkers, and guided metrics to assess treatment efficacy and neural activation.

“I am excited to work alongside Nexalin’s leadership and fellow SAB members to help guide the next generation of non-invasive neuromodulation therapies,” Huang said in a news release. “The intersection of neuroimaging, brain stimulation, and clinical science holds enormous potential for treating neurodegenerative disease.”

Recently, Nexalin’s proprietary neurostimulation device moved forward with a clinical trial that evaluated its treatment of anxiety disorders and chronic insomnia in Brazil. The first of Nexalin’s Gen-2 15-milliamp neurostimulation devices was shipped to São Paulo, Brazil, and the study will be conducted at the Instituto de Psiquiatria University Hospital (IPq-HCFMUSP). The shipments aim to support the launch of a Phase II clinical trial in adult patients suffering from anxiety and insomnia. The Nexalin Gen-2 15-milliamp neurostimulation device has also been approved in China, Brazil and Oman. Its Gen 1 device first received FDA clearance in 2003, according to the company's website.

The company also enrolled the first patients in its clinical trial at the University of California, San Diego, in collaboration with the VA San Diego Healthcare System for its Nexalin HALO, which looks to treat mild traumatic brain injury and post-traumatic stress disorder in military personnel and the civilian population.

Nexalin previously raised $5 million through a public stock offering.

making waves

Houston-based Nexalin Technology’s proprietary neurostimulation device will move forward with a new clinical trial evaluating its treatment of anxiety disorders and chronic insomnia in Brazil.

The first of Nexalin’s Gen-2 15-milliamp neurostimulation devices have been shipped to São Paulo, Brazil, and the study will be conducted at the Instituto de Psiquiatria university hospital (IPq-HCFMUSP). The shipments aim to support the launch of a Phase II clinical trial in adult patients suffering from anxiety and insomnia, according to a news release.

“Brazil is an important emerging market for mental health innovation, and this collaboration marks our first IRB-approved study in the region,” Mike White, CEO of Nexalin, said in the release.

The study will be led by Dr. Andre Russowsky Brunoni, who specializes in neuromodulation and interventional psychiatry. He currently serves as director of the interventional psychiatry division at IPq-HCFMUSP and this summer will join UT Southwestern in Dallas and its Peter O’Donnell Jr. Brain Institute as a professor of psychiatry.

The Phase II study plans to enroll 30 adults in São Paulo and assess the efficacy of Nexalin’s non-invasive deep intracranial frequency stimulation (DIFS™) of the brain in reducing anxiety symptoms and improving sleep quality, according to the company. Using the Hamilton Anxiety Rating Scale (HAM-A), the trial’s goal is a reduction in anxiety symptoms, and assessments of sleep onset latency, total sleep time, overall sleep quality, depressive symptoms and clinical impression of improvement. The company plans to share results in a peer-reviewed scientific journal.

“Anxiety and insomnia are very common conditions that often occur together and cause significant distress,” Brunoni added in the news release. “In this study, we are testing a new, non-invasive brain stimulation technology that has shown promising results in recent research. Our goal is to offer a safe, painless, and accessible alternative to improve people’s well being and sleep quality.”

The Nexalin Gen-2 15-milliamp neurostimulation device has been approved in China, Brazil, and Oman.

Houston ranks among 15 U.S. hot spots for women in tech

Ranking It

Houston is soaring among the best places in the U.S. for women in tech, a new report says. Houston ranked No. 15 nationwide in SmartAsset's new report, "Best and Worst Cities for Women in Tech — 2026 Study," which compared the 50 biggest U.S. cities across four metrics:

  • Gender pay gap — women's median earnings as a percentage of men’s median earnings in tech
  • The share of all tech workers that are women
  • The overall concentration of employment for tech workers, defined as "tech workers as a share of the local workforce"
  • Women tech workers’ median earnings, adjusted for regional price parity
For the purpose of the study, tech workers are defined as "city residents employed in computer and mathematical occupations." The study's findings show that fewer than 9,500 tech workers in Houston are women, or 25.6 percent of the total tech workforce in the city. In total, tech workers in general make up less than 3 percent of the Houston workforce.Despite the high ranking, women tech workers in Houston have a sizeable gap to cross to receive equal pay compared to their male counterparts in the same industry. Women tech workers make just over $97,000 in median earnings after adjusting for regional price parity, which is only 93 percent of what male tech workers make, SmartAsset found.

There are only two U.S. cities where women in tech earn more than what their male counterparts: Miami and Memphis, Tennessee. Women tech workers in Miami make an adjusted $88,650 in median earnings, or 101.7 percent of what men in tech make. In Memphis, women make $84,718 in adjusted earnings, or 101.5 percent of what men in tech earn.

The findings also assert that women remain underrepresented in the nation's overall tech sector, despite making up nearly half of the total workforce. Only 22.6 percent of the country's tech labor force is made up of women, according to the Equal Employment Opportunity Commission."Opportunities for women in tech can vary considerably by location, and these differences shape access to jobs, career advancement and earning potential," the report's author wrote. "In some places, women account for a larger share of tech workers, face narrower pay gaps and enjoy a stronger local labor market. In others, they may encounter a more challenging career environmentThe six other Texas cities that earned spots in the report are Austin (No. 6), Fort Worth (No. 26), Dallas (No. 32), Arlington (No. 38), San Antonio (No. 42), and El Paso (No. 49).

The top 10 best U.S. cities for women in tech are:

  • No. 1 – San Jose, California
  • No. 2 – Seattle, Washington
  • No. 3 – San Francisco, California
  • No. 4 – Atlanta, Georgia
  • No. 5 – Baltimore, Maryland
  • No. 6 – Austin, Texas
  • No. 7 – Oakland, California
  • No. 8 – Portland, Oregon
  • No. 9 – Boston, Massachusetts
  • No. 10 – Minneapolis, Minnesota
