Axonal swelling in the Purkinje cells of mice had no detrimental impact on firing rate or the speed at which axons transmit signals. At peak firing rate, axons with swellings were less likely to fail than those without.
The cerebellum underwent evolutionary changes that may have contributed to the development of language, culture, and tool use in humans, a new study reveals.
The effects of intoxication, such as slurred speech and poor coordination, are a result of the breakdown of alcohol products in the brain and not the liver.
Study sheds light on the brain chemistry involved in attention loss when a person drinks alcohol.
Disrupted cannabinoid signaling impairs learning by altering behavioral states.
High resolution imaging reveals the human cerebellum is 80% of the area of the cortex. The findings indicate this area of the brain likely grew larger as human behavior and cognition evolved.
Cortical thickness and regional brain connectivity pay an equally important role in linking brain and behavior.
Tufts researchers have developed neurotransmitter-lipid hybrids that help transport therapeutic drugs and gene editing proteins across the blood-brain barrier in mice.
Mouse study pinpoints the precise location in the brain where distracting stimuli are blocked, allowing for concentration on specific tasks. The findings could have implications for the treatment of ADHD and schizophrenia.
