A new study in rodents reveals a whisking oscillator that consists of a population of inhibitory neurons in the brainstem that fires in rhythmic bursts during whisking behaviors.
Researchers have developed a comprehensive "toolbox" to establish that the mobility of receptors exists in intact brain tissue, and this mobility is critical for certain types of memory.
Researchers identified a new mechanism by which auditory sensitivity is regulated. The mechanism can temporarily reduce sensitivity in the auditory system to protect itself from loud sounds that can cause hearing damage.
Researchers report they have identified the first natural light-gated potassium channel-rhodopsins.
A new study of the hippocampus reveals immature, plastic neurons are present in significant numbers during the entire lifespan. The findings shed new light on neuroplasticity.
Findings reveal sparse chemical connectivity as a generalized feature of the hypothalamus circuitry.
A rare genetic mutation that causes blindness also appears to be associated with above-average intelligence, a new study reports.
The motivation to exert sustained effort to achieve a goal following stress exposure depends on an individual's level of trait anxiety. The expression of CRHR1 in dopaminergic neurons in the ventral tegmental area connects anxiety to either boosted or diminished motivation levels.
Electric fields may represent information held in working memory, allowing the brain to overcome representational drift.
Blocking matrix metalloproteinases MMP2 and MMP9 can have the opposite effect on neuroplasticity depending on whether the brain is healthy or injured.
Human neurons have fewer ion channels compared to other animals. The reduced number of ion channels may have allowed the human brain to divert energy to other neural processes, researchers say.
In fruit flies, there is a second barrier in the brain where glial cells ensure a spatial separation for different functional compartments.
