Intro. to Cognitive Perceptual Impairment Flashcards
Define ‘Cognition’
How we use our brains to do things
Conscious & unconscious processes
Define ‘Sensory’
Information received from the outside world or body sent to the brain
Define ‘Perception’
The process of recognizing, organizing & interpreting information
- Impacted by sensory
- Shapes our thoughts & behaviours
Brain info. In regards to cognitive, sensory, & perceptual function?
97% body’s neural tissue (approx. 3 lbs)
2 Cerebral Hemispheres (left & right), divided into Lobes
Cerebral Cortex (folded outer surface of brain):
- Sunken parts = Suki
- Raised parts = Gyri
‘Corpus Collosum’ job?
Allows communication to both sides of central hemispheres by switching cerebral hemisphere body control to opposite side of body
Thalamus?
Gatekeeper
Relays motor and sensory signals as they travel to the brain’s cerebral cortex
Hypothalamus?
Maintains homeostasis
Regulates autonomic nervous system:
controls body temperature, hunger, sleep, blood pressure
Grey matter vs White matter
Grey = Nuclei (cells)
White = Myelinated nerve fibers (axons)
Frontal lobe?
Voluntary movement, Behaviour(personality), Self control, Decision making, Problem solving, Planning
Occipital lobe?
Vision
Parietal lobe?
Sensory,
Memory,
Recognition
Temporal lobe?
Emotion,
Hearing,
Music
Cerebellum?
Balance, Movement, Posture
Traumatic Brain Injury impact on brain function?
Confusion Poor memory & concentration Sensory loss/reduction Blurred vision Speech difficulties
Stroke?
Loss of balance & coordination
Trouble speaking & understanding
Paralysis/numbness face, arm, leg
Vision problems, one or both eyes
Dementia?
Suspiciousness
Irritability
Depression/anxiety
Difficulty finding/remembering where things are
