The strength of pattern completion during memory retrieval, indexed by hippocampal activity and cortical reinstatement, explains within- and across-individual variability in episodic memory in older adults.
Rats exposed to a single stressful event experience days-long constitutive activation of the kappa opioid receptor at inhibitory synapses in part of the brain’s reward system, which increases their drug-seeking behavior.
Prostate cancer resistance to androgen receptor antagonist therapy occurs by way of tumors impeding local glucocorticoid metabolism and inactivation and thereby permitting sustained glucocorticoids to stimulate up-regulated glucocorticoid receptor.
Akt mediated S14 phosphorylation of Id2 augments its protein stability and growth cone localization, promoting growth cone formation and axon growth in the developing neuron and contributing to axon regeneration in the damaged hippocampus slice.
Novel spatial representations by hippocampal cellular assemblies develop on the framework of preconfigured hippocampal networks whose homeostatic synaptic reorganization is accelerated by prior experience and CA3 NMDAR-dependent plasticity.
