Nasal spray shows promise in combating Alzheimer's

A future treatment for Alzheimer disease may involve a nasal spray. Researchers at Università Cattolica and Fondazione Policlinico Universitario A. Gemelli IRCCS have discovered that by inhibiting the brain enzyme S-acyltransferase (zDHHC) through a nasal-spray drug, they can counteract the cognitive decline and brain damage typical of the disease.

Dopamine and serotonin balance reward learning in opposing ways

If you've heard of two of the brain's chemical neurotransmitters, it's probably dopamine and serotonin. Never mind that glutamate and GABA do most of the work - it's the thrill of dopamine as the "pleasure chemical" and serotonin as tender mood-stabilizer that attract all the headlines.

Researchers identify brain circuit behind sexual rejection in females

A team from the Champalimaud Foundation (CF) has pinpointed a critical neural circuit for sexual rejection, identifying a set of brain cells that play a crucial role in determining whether a female accepts or rejects mating attempts based on her reproductive cycle.

Brain volume loss linked to Alzheimer's treatment may be caused by amyloid plaque removal

A loss of brain volume associated with new immunotherapies for Alzheimer's disease may be caused by the removal of amyloid plaques, rather than the loss of neurons or brain tissue, finds a study led by UCL researchers.

From womb to midlife: Prenatal immune disruptions reshape memory and cognitive aging

Prenatal exposure to maternal pro-inflammatory cytokines shapes memory and immune function in offspring, with sex-specific effects emerging over 50 years.

NREM sleep boosts cognitive performance through brain synchronization

While it's well known that sleep enhances cognitive performance, the underlying neural mechanisms, particularly those related to nonrapid eye movement (NREM) sleep, remain largely unexplored.

Pioneering protocol sheds light on NMDA receptor distribution in Alzheimer's brains

Researchers from the Institute for Neurosciences (IN), a joint center of the Miguel Hernández University of Elche (UMH) and the Spanish National Research Council (CSIC), who are also part of the Network Center for Biomedical Research in Neurodegenerative Diseases (CIBERNED) and the Alicante Institute for Health and Biomedical Research (ISABIAL), have developed a cellular fractionation protocol.

Study reveals how brainstem neurons control eye movements

Working with week-old zebrafish larva, researchers at Weill Cornell Medicine and colleagues decoded how the connections formed by a network of neurons in the brainstem guide the fishes' gaze.
