Cognitive Neuroscience Flashcards
metabolic center of the neuron; it contains mechanisms to keep cell alive
Cell body
the branch out from the cell body is to receive signals from pther neurons
Dendrites
are usually long processes that transmit signals to other neurons
Axons (Nerve Fibers)
Small gap between the end pf neuron axon & densdrites
Synapse
this forms a groups amof interconnected neurons
Neural circuits
chemical messagers
Neurotransmitters
Fight or flight
Adrenaline
Concentration
Noradrenaline
Pleasure
Dopamine
Mood
Serotonin
Calming
Gaba
Learning
Acetylcholine
Memory
Glutamate
Euphoria
Endorphins
states that everything a person experience is based pn representations in the person’s nervous systems
Principle of neural representation
it responded to specific stimulus feastures such as orientation, movement, and length.
Feature detectors neurons
in which the structure of the brain in changed by experience
Experience dependent plasticity
specific finctions are served by specific areas of the brain.
Localization of function
the study of people’s behavior with brain damage
neuropsychology
the idea that the brain operated as an indivisible whole as opposed to specialized areas.
cortical equipotentiality
He published work based on his study of patoents who had sugfered brain damage due to stroke
Paul Broca
These strokes damages the frontal lobe
Broca’s Area
Patients with this problems— slow, labored, ungrammatical speech caused by damage to broca’s area
Broca’s Aphasia
He describe a number of patients who had damage to an area in their temporal lobe
Carl Wernicke
