The slice preparation or brain slice is a laboratory technique in electrophysiology that allows the study of neurons from various brain regions in isolation from the rest of the brain, in an ex-vivo condition. Brain tissue is initially sliced via a tissue slicer then immersed in artificial cerebrospinal fluid (aCSF) for stimulation and/or ...
The claustrum (Latin, meaning "to close" or "to shut") is a thin sheet of neurons and supporting glial cells in the brain, that connects to the cerebral cortex and subcortical regions including the amygdala, hippocampus and thalamus.
Hypotheses expressed in terms of the model parameters are assessed at each voxel with univariate statistics. Analyses may examine differences over time (i.e. correlations between a task variable and brain activity in a certain area) using linear convolution models of how the measured signal is caused by underlying changes in neural activity.

The selection of the common swift as a model stemmed from observations elucidating the fact that the common swift left its nest at night, only returning in the early morning. Still, evidence for USWS is strictly circumstantial and based on the notion that if swifts must sleep to survive, they must do so via aerial roosting as little time is ...
When you have healthy sleep, the glymphatic system in your brain—which pumps out waste products—is more active and efficient, Winter explains. But on the flip side, when you have poor sleep ...
It's possible that sundowning in dementia patients is caused by a combination of hormonal changes, brain deterioration or damage that has occurred, environmental factors, disruption to a person's ...
It is believed to play a role in some cases of human epilepsy. [7] [8]It has also been implicated in working memory [9] and drug addiction. [10]It has been suggested that the dorsal subiculum is involved in spatial relations, and the ventral subiculum regulates the hypothalamic-pituitary-adrenal axis.
