Week 7: Neuroscience and Biopsychology Flashcards
(9 cards)
Neurotransmitters: definition
Chemical messengers that transmit signals from one neuron to another.
Neurotransmitters: Functions
Acetylcholine
Norepinephrine
Serotonine
Dopamine
Gamma-Amino Butyric Acid
Glutamate
Endorphins
Acetylcholine:
memory/movement
Norepinephrine: Alertness/mood/learning
Serotonine:
mood/memory/less appetite
Dopamine: Movement/reward/concentration
GABA:
movement/sleep
Glutamate:
learning/memory
Endorphins:
pleasure/pain
Neuroplasticity:
* The brain’s ability to reorganise and form n__ n_____ connections
* Allows adaptation, l__________, and r___________ from injuries
* Crucial for r________________ and treatment
* Supports the idea of “u___ it or l___ it”
Neuroplasticity:
* The brain’s ability to reorganise and form new neural connections
* Allows adaptation, learning, and recovery from injuries
* Crucial for rehabilitation and treatment
* Supports the idea of “use it or lose it”
Neurogenesis
Formation of new neurons.
Neurodegenerative Disorders x3
Alzeimer’s
Parkinson’s
Huntington’s
Perceptual Disturbances:
Visual agnosia
Prosopagnosia
Simultanagnosia
Hemineglect
VA: inability to identify an object, but can see it.
P: inability to recognise faces, but can see them
S: can only perceive parts of a scene
H: pay attention to information coming from only one side of the world.
Specific Brain Impairments:
