-
Perceptual learning
learning to recognize a particular stimulus, dorsal stream-->object location, ventral stream--->object recognition
-
stimulus-response learning
the ability to learn to preform a particular behavior when a particular stimulus is present
-
Long term potentiation (LTP)
a long-term increase in the excitability of a neuron to a particular synaptic input caused by repeated high-frequency activity of that input, postsynaptic activity increased
-
hippocampal formation
undergoes LTP, includes the dentate gyrus and subiculum
-
Population EPSP
an evoked potential that represents the excitatory postsynaptic potenials of a population of neurons, from the dentate gyrus and become more tight (responsive) over time
-
Long-term depression
postsynaptic activity decreased
-
Operant conditioning
the means by which we profit from experience, start out depending on basal ganglia for response to stimulus, with repition, only basakl ganglia; positive reinforcement activates dopaminergic neurons in VTA and nucleus accumbens(involved in learning)
-
Motor learning
learning to make a new response, requires sensory guidence from the enviornment
-
Relational learning
learning the relationship among individual stimuli, important for making and retrieval of long-term memories
-
Declaritive memories
can be consciously recalled (explicit)
-
Declaritive memories: semantic
when is your birthday
-
Declaritive memories: episodic
what did you do for your birthday?
-
Non-declaritive memories
cannot be consciously recalled (implicit)
-
Non-declaritive memories: procedural
riding a bike
-
Non-declaritive memories: primed
being reminded of grandma after a familiar smell
-
Retrograde Amnesia
preceed some distrubance to the brain, such as head injury; cannot remember events prior to brain damage
-
Anterograde amnesia
events that occur after some disturbance to the brain, such as head injury or certain degenerative brain diseases; cannot remember events that occured after damage
-
Korsokoff's syndrome
permenant anterograde amnesia caused by brain damage, usually resulting from chronic alchoholism, patients often confabulate events, severe malnutrition, usually from chronic alchoholism
