Houston startup, researchers awarded millions to develop Brain Mesh implant

brain health

Houston startup Motif Neurotech and several Rice research groups have been selected by the United Kingdom's Advanced Research + Invention Agency (ARIA) to participate in its inaugural Precision Neurotechnologies program. The program aims to develop advanced brain-interfacing technologies for cognitive and psychiatric conditions.

ARIA will invest $84.2 million over four years in projects that “explore and unlock new methods to interface with the human brain at the circuit level,” according to a news release.

Three of the four Rice labs will collaborate with Houston health tech startup Motif Neurotech to develop Brain Mesh, which is a distributed network of minimally invasive implants that can stimulate neural circuits and stream neural data in real time. The project has been awarded approximately $5.9 million.

Motif Neurotech was spun out of the Rice lab of Jacob Robinson, a professor of electrical and computer engineering and bioengineering and CEO of Motif Neurotech. It will be developed in collaboration with U.K.-based startup MintNeuro, which will help develop custom integrated circuits that will help to miniaturize the implants, according to a separate release.

Robinson will lead the system and network integration and encapsulation efforts for Mesh Points implants. According to Rice, these implants, about the size of a grain of rice, will track and modulate brain states and be embedded in the skull through relatively low-risk surgery.

The Rice lab of Valentin Dragoi, professor of electrical and computer engineering at Rice and the Rosemary and Daniel J. Harrison III Presidential Distinguished Chair in Neuroprosthetics at Houston Methodist, will conduct non-human primate experimental models for Brain Mesh. Kaiyuan Yang, associate professor of electrical and computer engineering who leads the Secure and Intelligent Micro-Systems Lab at Rice, will work on power and data pipeline development to enable the functional miniaturization of the Mesh Points.

“Current neurotechnologies are limited in scale, specificity and compatibility with human use,” Robinson said in a news release. “The Brain Mesh will be a precise, scalable system for brain-state monitoring and modulation across entire neural circuits designed explicitly for human translation. Our team brings together a key set of capabilities and the expertise to not only work through the technical and scientific challenges but also to steward this technology into clinical trials and beyond.”

The fourth Rice lab, led by assistant professor of electrical and computer engineering Jerzy Szablowski, will collaborate with researchers from three universities and two industry partners to develop closed-loop, self-regulating gene therapy for dysfunctional brain circuits. The team is backed by an award of approximately $2.3 million.

“Our goal is to develop a method for returning neural circuits involved in neuropsychiatric illnesses such as epilepsy, schizophrenia, dementia, etc. to normal function and maybe even make them more resilient,” Szablowski said in a news release.

Neurological disorders in the U.K. have a roughly $5.4 billion economic burden, and some estimates run as high as $800 billion annually in terms of economic disruptions in the U.S. These conditions are the leading cause of illness and disability with over one in three people impacted according to the World Health Organization.

Electricity startup expands to Houston with promise of backup battery power

Power Up

An Austin startup that sells electricity and couples it with backup power has entered the Houston market.

Base Power, which claims to be the first and only electricity provider to offer a backup battery, now serves the Houston-area territory served by Houston-based CenterPoint Energy. No solar equipment is required for Base Power’s backup batteries.

The company is initially serving customers in the Cy-Fair, Spring, Cinco Ranch and Mission Bend communities, and will expand to other Houston-area places in the future.

Base Power already serves customers in the Austin and Dallas-Fort Worth markets.

The company says it provides “a cost-effective alternative to generators and solar-battery systems in an increasingly unreliable power grid.”

“Houston represents one of the largest home backup markets in the world, largely due to dramatic weather events that strain the power grid,” says Base Power co-founder and CEO Zach Dell, son of tech billionaire Michael Dell. “We’re eager to provide an accessible energy service that delivers affordable, reliable power to Houston homeowners.”

After paying a $495 or $995 fee that covers installation and permitting, and a $16- or $29-per-month membership fee, Base Power customers gain access to a backup battery and competitive energy rates, the company says. The startup is waiving the $495 setup fee for the first 500 Houston-area homeowners who sign up and make a refundable deposit.

With the Base Power backup package, electricity costs 14.3 cents per kilowatt-hour, which includes Base Power’s 8.5 cents per kilowatt-hour charge and rates charged by CenterPoint. The average electric customer in Houston pays 13 cents per kilowatt-hour, according to EnergySage.

“Base Power is built to solve a problem that so many Texans face: consistent power,” says Justin Lopas, co-founder and chief operating officer of Base Power and a former SpaceX engineer. “Houstonians can now redefine how they power their homes, while also improving the existing power grid.”

Founded in 2023, Base Power has attracted funding from investors such as Thrive Capital, Valor Equity Partners, Altimeter Capital, Trust Ventures, and Terrain. Zach Dell was previously an associate on the investment team at Thrive Capital.
