electroconvulsive therapy (ect) is an efficient treatment for several neuropsychiatric disorders however a large number of patients develop memory impairment after ect. different studies both on animals and human suggest that vasopressin has positive effects on memory and improves cognitive functions. in this randomized, double-blind controlled clinical trial, 50 patients with psychiatric disor...

The influence of circadian rhythms on memory has long been studied; however, the molecular prerequisites for their interaction remain elusive. The hippocampus, which is a region of the brain important for long-term memory formation and temporary maintenance, shows circadian rhythmicity in pathways central to the memory-consolidation process. As neuronal plasticity is the translation of numerous...

Objective(s): Neurodegeneration is an outcome of Methamphetamine (METH) abuse. Studies have emphasized on the neuroprotective properties of lithium. The current study is designed towards evaluating the role of Akt-1/GSK3 and CREB-BDNF signaling pathways in mediating lithium neuroprotection against METH-induced neurodegeneration in rats. Materials and ...

Nonassociative odor learning paradigms are often used to assess memory, social recognition and neuromodulation of olfactory pathways. We here use a modified object recognition paradigm to investigate how an important task parameter, delay between encoding and recall trials, affects the properties of this memory. We show that both memory for a previously investigated odorant and discrimination o...

The neurobiological substrate of learning process and persistent memory storage involves multiple brain areas. The neocortex and hippocampal formation are known as processing and storage sites for explicit memory, whereas the striatum, amygdala, neocortex and cerebellum support implicit memory. Synaptic plasticity, long-term changes in synaptic transmission efficacy and transient recruitment of...
