Ionizing radiation impairs the formation of trace fear memories and reduces hippocampal neurogenesis.

29 Sep 2009 Long-term cognitive impairments are a feared consequence of therapeutic cranial irradiation in children as well as adults. Studies in animal models suggest that these deficits may be associated with a decrease in hippocampal granule cell ... Read more...

Light-dark cycle memory in the mammalian suprachiasmatic nucleus.

14 Sep 2009 The mammalian circadian oscillator, or suprachiasmatic nucleus (SCN), contains several thousand clock neurons in its ventrolateral division, many of which are spontaneous oscillators with period lengths that range from 22 to 28 h. In complete ... Read more...

Mobile phone exposure and spatial memory.

30 Dec 2008 Radiofrequency (RF) emission during mobile phone use has been suggested to impair cognitive functions, that is, working memory. This study investigated the effects of a 2 1/2 h RF exposure (884 MHz) on spatial memory and learning, using a ... Read more...

Technical information about 'Memory'

Definition: Complex mental function having four distinct phases: (1) memorizing or learning, (2) retention, (3) recall, and (4) recognition. Clinically, it is usually subdivided into immediate, recent, and remote memory.
