Neurotrauma cognition

Neurotrauma & Cognition


Concussion cognition

Concussion & Cognition

  • Studies on executive function & attention post-concussion

  • Extent of injury in developing brains (adolescents) compared to adults?

  • Greater risk of subsequent injury w/ premature return to sport


Concussion cognition1

Concussion & Cognition

  • Subtle deficits can persist, despite self report

    • Decline in academic performance

    • Body movement, gait

    • Task-shifting

Research in tbi

Research in TBI

Cognitive effects of one season of head impacts in a cohort of collegiate contact sport athletes: What lifestyle factors might delay cognitive decline/ dementia?; McAllister et al. (assigned reading)


Research in tbi1

Research in TBI

  • Millions suffer brain injury each year

    • Many are sub-concussive injuries

  • Test effect of repetitive traumas over season of collegiate sports

    • 214 football & hockey players

    • 45 non-contact sport players


Research in tbi2

Research in TBI

  • ImPACT, neuropsychological, cognitive testing

    • Pre & post season

  • Head impacts measured via HIT helmets

    • Rotational & linear acceleration

    • Location, force of impacts

  • Average 469 impacts


Research in tbi3

Research in TBI

  • Significantly higher % of contact athletes performed below predicted postseason score

    • Subgroup w/ cognitive impact - higher magnitudes/frequencies

  • No differences pre-season

    • Suggests lack of residual effects

  • Confounds?


Assistive technology

Assistive Technology


Braingate

BrainGate

Recording cognition

Recording Cognition

  • Implantable, rechargeable, wireless brain sensor - signals from 100 neurons in vivo

    • Freely moving

    • Natural cognitive behaviors

  • Connections betw/ multiple sensors

  • Transition to human research, assistive tech


Connectome project

Connectome Project

  • Mapping brain connections

    • Fiber pathways

    • 100 billion neurons, trillions of connections

  • Abnormalities may underlie psychiatric, cognitive disorders


Cognition a i

Cognition & A.I.

“Kismet”


Cognitive robotics

Cognitive Robotics

  • “Create” cognition in learning robot

    • Reasoning, decision making

    • Perceptual, attentional skills

    • Complex motor coordination

    • Language, communication

  • Act in the real world - learning


Modeling human cognition

Modeling Human Cognition

  • Interest in modeling human emotion

  • Developing & expressing emotion in interaction w/ humans


Cognition technology apr 29 2014

“Nao”

  • Postures, gestures & movements (non-verbal)

  • Modeled on early attachment behaviors

    • Learn as children do

Dr. Cañamero, University of Hertforshire


Cognition technology apr 29 2014

“Nao”

  • Adapt to actions/moods of caregiver

    • Preference, attachment

    • Learn via feedback, strengthen “bond”

    • Shared experience, memory

  • Express variety of emotions

    • “Chooses” when to display


Therapeutic value

Therapeutic Value

  • Companions for elderly, ill

  • Social learning for autistic children

  • Support for hospitals, treatment centers

    • Reduce anxiety

    • Interact w/ children


Cognition technology apr 29 2014

“Nexi”

  • Non-verbal cues for trustworthiness, dishonesty

    • Arm placement

    • Facial movements

  • Prisoner’s Dilemma

    • Response to human vs. machine

Cyn­thia Breazeal, MIT

Dr. DeSteno, Northeastern University


Future of robotics

Future of Robotics?

  • Can robots form social bonds, relationships w/ human counterparts?

  • Results suggest humans willing & able to assign moral intent to Nexi

  • The “uncanny valley”
