Serotonin-producing neurons in the brainstem release serotonin throughout the brain during moments of novel social encounters. The release of serotonin stimulates neurons in the medial septum via a subtype of serotonin-sensitive receptor molecules. Blo…
Mouse study identifies specific neurons and a signaling pathway to regions of the hindbrain that mediate sexual reproductive activity and physical activity that appear to influence activity behaviors during ovulation. The findings may provide valuable …
The planar cell polarity (PCP) signaling pathway appears to play a significant role in the formation and maintenance of a large number of synapses.
Study shows chronic hyperglycemia impairs working memory performance and alters fundamental aspects of working memory brain networks. The findings strengthen the link between type 2 diabetes and Alzheimer’s disease.
The hippocampus brings pieces of memories together over time and forms them into connective, narrative memories.
Preliminary new findings are raising concerns about the long-term effect of mild COVID-19 infection on neurological health and cognition.
Mouse study reveals chronic stress affects neurogenesis in the dentate gyrus.
Researchers identified specific receptors for acetylcholine that reroute information flow through memory circuits in the hippocampus. The findings could have implications for the development of drugs to help enhance or protect memory from diseases asso…
Altered behaviors associated with LSD may be caused by a reduction in the normal communication between the hippocampus and visual cortex.
Amyloid-beta proteins created in the liver are carried in the blood by lipoproteins to the brain. This results in neurodegeneration, brain atrophy, and inflammation, which are common features of Alzheimer’s disease.
Pain could be an under-recognized clinical manifestation for patients with specific autoantibodies that target neural proteins.
Findings shed light on the mechanisms underlying brain damage in microgravity.
The function of the opioid system is connected to eating triggered by external stimuli. The findings could lead to the development of new therapies that target the opioid system to reduce obesity.
Combining virtual reality with neuroimaging, researchers identify how the brain perceives and remembers a novel place or landscape.
The habenula relays external information, such as sight and smell, along with internal states associated with emotion and learning to brain regions that govern adaptive behaviors.
Diet and exercise can influence hippocampal neurogenesis, researchers say. Poor nutrition and lack of exercise have detrimental effects on hippocampal neurogenesis, increasing the risk for dementia.
Study reaffirms findings that the gut microbiome may play a significant role in cognitive decline. Researchers found, in mice, a ketogenic diet, hypoxia, and the Bilophila wadsworthia bacteria impaired the hippocampus, leading to signs of cognitive dec…
Study identifies the role a specific protein plays in regulating the development of inhibitory synapses in the hippocampus in the context of anxiety-related behaviors.
Researchers report on how a cluster of neurons in the hippocampus may directly regulate metabolism.
A study spanning 17 years has found children born and raised in poverty had smaller subcortical brain regions, including the hippocampus, caudate, putamen, and thalamus. These brain areas also showed less growth over time.
