New research helps explain how Ritalin sharpens attention

Researchers found animals that had taken methylphenidate performed better on a visual task of attention, and that the improvement happened exactly when that same metric of neuron activity shifted.

Scientists detail brain dynamics implicated in neurological conditions

Researchers used fMRI and a genetic mouse model to study the effects of a neurotransmitter on brain network functional connectivity, a dynamic process crucial for human health and behavior.

Neural pathway key to sensation of pleasant touch identified

Researchers have identified a specific neuropeptide and a neural circuit that transmit pleasant touch from the skin to the brain. The findings eventually may help scientists better understand and treat disorders characterized by touch avoidance and imp…

Atherosclerosis: How diseased blood vessels communicate with the brain

Scientists have been able to demonstrate that nerve signals are exchanged between arteries and the brain in atherosclerosis.

Seven hours of sleep is optimal in middle and old age, say researchers

Seven hours is the ideal amount of sleep for people in their middle age and upwards, with too little or too much little sleep associated with poorer cognitive performance and mental health, say researchers.

New brain learning mechanism calls for revision of long-held neuroscience hypothesis

Just one single neuron can realize deep learning algorithms, which previously required an artificial complex network consisting of thousands of connected neurons. This discovery is expected to have important implications on future AI hardware.

Neuronal plasticity in chronic pain-induced anxiety revealed

Researchers have shown how chronic pain leads to maladaptive anxiety in mice, with implications for treatment of chronic pain-related psychiatric disorders in humans.

Researchers investigate connection between loss of motivation and Alzheimer’s disease progression

Researchers are studying why neuropsychiatric symptoms, such as apathy and irritability, appear in most Alzheimer’s disease patients before the onset of memory loss.

Anesthetic drastically diverts the travels of brain waves

Under propofol general anesthesia very slow frequency traveling waves transform and dominate, redirecting and disrupting the higher frequency traveling waves associated with conscious function.

Gastrointestinal issues linked with anxiety, social withdrawal for kids with autism

A new study found a ‘bi-directional’ relationship between gastrointestinal issues and internalized symptoms in children and adolescents with autism — meaning the symptoms seem to be impacting each other simultaneously. The findings could influence fut…
