Neuro Jungle is a Division of 3DpreMotorSkill Technologies, LLC, a research and development company based in Tallahassee, Florida. We build technologies to help survivors of ABI “Acquired Brain Injury” move impaired limbs, for example:

  1. video-game-like ‘pre-action games and exercises’ (PAGE) featuring personal survivor control of virtual limbs; and
  2. a wearable hand manipulation device (WHMD) coded to simultaneously manipulate an impaired hand as a virtual hand is independently controlled to move by each survivor

Survivors controlling virtual limb movements are pre-training to make physical limb movements. We call our ‘games’ Pre-Action Games & Exercises (PAGE). Basically, PAGE is a platform of fun and useful survivor-manipulations of virtual limbs designed to assist brain-to-impaired-limb communications. In addition to cognitive exercise the WHMD provides physical manipulation/exercise.

WE are proud and humbled to be working in areas of significant individual and societal needs. –  Our Mission
Our mission is supplemental care for survivors of stroke and traumatic brain injury.

WHY we are The PPN
If you were to peer inside the pedunculopontine nucleus (PPN) it resembles a jungle: a massive number and variety of nerve cells all with particular jobs to do. The PPN is a brainstem locomotive center processing sensory and behavioral information. It communicates with the motor areas of the spinal cord and participates in motor control and muscle tone.

Society’s need for
Our website makes the case for’s need for donations … in brief and superficially, here is the case for the US society’s need:

The US experiences 800,000 strokes each year of which there are 140,000 deaths.

Do the math, 560,000 survivors each year.

560,000 survivors would fill 5.6 stadiums each with 100,000 person capacity.

The total number of US survivors is 6.5 to 7.0 million.

6.5 to 7.0 million total survivors would fill 65 to 70 such stadiums.

European Union
The total population of the 28 European Union Member States is about 510 million (1.64 times greater than the US population). The annual and total number of acquired brain injury survivors (stroke and TBI) is likely to exceed US survivors.

Neuro Jungle Founder

Vince Macri is an inventor with multiple patents in the field of video game-like technology. His work centers on assisting survivors of stroke left with intact, but impaired hemiplegic limbs. His projects include traumatic brain injured individuals and others whose conditions impede brain-to-body-communications. Vince has worked with 47 ABI survivors in two clinical trials in the U.S. and Europe. Vince’s technology supports survivors’ efforts to regain brain-planning to use physical limbs. Survivors control surrogate, virtual limbs, simulate purposeful physical limb movements and receive virtual visuomotor feedback. His recent invention is a combination of virtual, pre-action games and exercises (PAGE) with a powered orthotic device. The initial device is a wearable hand manipulation device (WHMD). The WHMD gently manipulates a survivor’s physical impaired hand simultaneously with a generated virtual impaired hand that is controlled by the ABI survivor. Vince is engaged in raising funds to support additional developments and clinical trials. Vince’s goal is to deliver the PAGE platform and WHMD to survivors, at home, using any computer, laptop, tablet or mobile phone device. Vince is founder and CEO of 3DPreMotorSkill Technologies LLC.

She has a passion for education and has been an adjunct faculty in the University of New Hampshire Occupational Therapy Department since 2014.

Megan Murnane


Megan graduated from the University of New Hampshire’s occupational therapy master’s program in 2013 and has experience working with adults, adolescents, children, infants and families in early intervention, school and acute care (pediatric and neonatal intensive care) settings. Megan is passionate about people and finds so much joy in providing occupational therapy services to a variety of patients, whether be it through direct evaluation/treatment or research.

Douglas Simmons


C. Douglas Simmons, PhD, OTR/L, FAOTA, is Professor and Program Director of the Master of Science Occupational Therapy Program at MCPHS University. Dr. Simmons has over 19 years of academic experience and 28 years of experience in occupational therapy. His clinical area is working with adults who have survived an acquired brain injury and this includes experience in all practice settings for these individuals. He has multiple national and international publications and presentations on topics related to this population and has also initiated community programming for these individuals. Dr. Simmons assisted in the development of the Evaluation of Social Interaction, a tool that has guided social program development for adults with acquired brain injury.
