Question

Which of following statements about learning and memory is FALSE?

		Memory is all or none: either memories of all types are completely intact or completely lost.
		In Pavlovian conditioning the development of the conditioned response requires pairing of the conditioned stimulus and the unconditioned stimulus.
		Place cells are located in the hippocampus.
		Long term potentiation involves a growth of dendritic spines in the postsynaptic cell.

Answer 1

First statement is false because only the cases of long term memory are either intact or lost completely .The short term memories do not present with a all or none

Second statement is correct because the Pavlovian conditioning is associated with a potent and neutral stimulus of which one is conditioned and other one is not .Example:Salivation in dog when bell rings .

Third statement is true because place cells which show a cognitive mapping word an organisms is present in the hippocampal region of the brain.

Fourth statement is true because in long term potentiation there is a translation which occurs in dendritic mRNA which results in dendritic spines in the post synaptic cell

Therefore first  statement is wrong
