Mouse study reveals chronic stress affects neurogenesis in the dentate gyrus.
Deficits in the dentate gyrus function that causes memory problems may be associated with epileptic seizures a new study reports. The abnormal activity leads to over-extinction, spurring on seizures.
The findings support a continuous model of neurogenesis throughout development and adulthood.
A specialized area of the mouse brain called the SuM specializes in detecting novel experiences. Within this brain area, responses to social novelty, or experiences related to unknown individuals, were segregated from those related to unfamiliar places, before being sent to areas of the brain associated with memory.
Using laboratory mice, researchers show anesthesia's neurotoxic effects depend upon the age of the neurons in the brain and not the age of the animal undergoing anesthesia.
Summary: Using three different types of brain imaging, the researchers found evidence of the three types of changes in the...
Researchers use virtual reality to discover how the brain assembles contextual memories.
