Salty immune cells surrounding the brain linked to hypertension-induced dementia

A study suggests that the response of immune system cells inside the protective covering surrounding the brain may contribute to the cognitive decline that can occur in a person with chronic high blood pressure. This finding may shed light on new ways …

Study identifies peptide as key mediator in heavy alcohol drinking

Researchers have identified that a peptide called pituitary adenylate cyclase activating polypeptide (PACAP), is involved in heavy alcohol drinking. In addition, they have discovered that this peptide acts in the BNST area.

Human behavior guided by fast changes in dopamine levels

A new study shows that dopamine release in the human brain plays a crucial role in encoding both reward and punishment prediction errors. This means that dopamine is involved in the process of learning from both positive and negative experiences, allow…

Scientists use A.I.-generated images to map visual functions in the brain

Researchers have┬ádemonstrated the use of AI-selected natural images and AI-generated synthetic images as neuroscientific tools for probing the visual processing areas of the brain. The goal is to apply a data-driven approach to understand how vision i…

Combined use of alcohol and THC can affect rat brains, study finds

The increased legalization of cannabis over the past several years can potentially increase its co-use with alcohol. Concerningly, very few studies have looked at the effects of these two drugs when used in combination. In a series of new studies, rese…

Researchers discover new classes of RNA for learning and memory

Researchers have discovered a new way ribonucleic acid (RNA) impacts fear-related learning and memory. Researchers demonstrated that a noncoding RNA known as Gas5 coordinates the trafficking and clustering of RNA molecules inside the long processes of …

Brain waves usually found in sleep can protect against epileptic activity

Slow waves that usually only occur in the brain during sleep are also present during wakefulness in people with epilepsy and may protect against increased brain excitability associated with the condition, finds a new study.

Loss of auditory nerve fibers uncovered in individuals with tinnitus

Researchers have uncovered that tinnitus, an incurable persistent ringing or other sounds in the ears, might result from underlying auditory nerve damage that can’t be detected on conventional hearing tests. The work builds upon previous research into

Lost brain function restored in mice after stroke

Researchers have succeeded in restoring lost brain function in mouse models of stroke using small molecules that in the future could potentially be developed into a stroke recovery therapy.

Distinct brain activity triggered by memories of trauma

It is well known that people who have lived through traumatic events like sexual assault, domestic abuse, or violent combat can experience symptoms of post-traumatic stress disorder (PTSD), including terrifying flashbacks, severe anxiety, and uncontrol…
