Impaired spatial learning in α-calcium-calmodulin kinase II mutant mice

AJ Silva, R Paylor, JM Wehner, S Tonegawa - Science, 1992 - science.org
Although long-term potentiation (LTP) has been studied as the mechanism for hippocampus-
dependent learning and memory, evidence for this hypothesis is still incomplete. The mice …

Deficient hippocampal long-term potentiation in α-calcium-calmodulin kinase II mutant mice

AJ Silva, CF Stevens, S Tonegawa, Y Wang - Science, 1992 - science.org

Autophosphorylation at Thr286 of the α Calcium-Calmodulin Kinase II in LTP and Learning

KP Giese, NB Fedorov, RK Filipkowski, AJ Silva - Science, 1998 - science.org
The calcium-calmodulin–dependent kinase II (CaMKII) is required for hippocampal long-

Effects of cAMP simulate a late stage of LTP in hippocampal CA1 neurons

U Frey, YY Huang, ER Kandel - Science, 1993 - science.org
Hippocampal long-term potentiation (LTP) is thought to serve as an elementary mechanism
for the establishment of certain forms of explicit memory in the mammalian brain. As is the …

Learning mechanisms: the case for CaM-KII

J Lisman, RC Malenka, RA Nicoll, R Malinow - Science, 1997 - science.org
What are the long-lasting changes that occur in your brain as you learn new information? It
is generally thought that memory is due to persistent modification of the strength of …

Potentiated transmission and prevention of further LTP by increased CaMKII activity in postsynaptic hippocampal slice neurons

DL Pettit, S Perlman, R Malinow - Science, 1994 - science.org
Calcium-calmodulin-dependent protein kinase II (CaMKII) is a necessary component of the
cellular machinery underlying learning and memory. Here, a constitutively active form of this …

Storage of spatial information by the maintenance mechanism of LTP

E Pastalkova, P Serrano, D Pinkhasova, E Wallace… - science, 2006 - science.org

induction and maintenance phases. Testing the hypothesis that the mechanism of LTP …

Postsynaptic calcium is sufficient for potentiation of hippocampal synaptic transmission

RC Malenka, JA Kauer, RS Zucker, RA Nicoll - Science, 1988 - science.org
Brief repetitive activation of excitatory synapses in the hippocampus leads to an increase in
synaptic strength that lasts for many hours. This long-term potentiation (LTP) of synaptic …

An essential role for protein phosphatases in hippocampal long-term depression

RM Mulkey, CE Herron, RC Malenka - Science, 1993 - science.org
The effectiveness of long-term potentiation (LTP) as a mechanism for information storage
would be severely limited if processes that decrease synaptic strength did not also exist. In …
