Octopuses given mood drug 'ecstasy' reveal genetic link to evolution of social behaviors in humans

By studying the genome of a kind of octopus not known for its friendliness toward its peers, then testing its behavioral reaction to a popular mood-altering drug called MDMA or 'ecstasy,' scientists say they have found preliminary evidence of an[…]

Gut sense: Neural superhighway conveys messages from gut to brain in milliseconds

Searching for a more direct connection between the gut and the brain, researchers were shocked to see that distance spanned by a single synapse, relaying the signal in less than 100 milliseconds, less than the blink of an eye. The[…]

Gambling monkeys help scientists find brain area linked to high-risk behavior

Monkeys who learned how to gamble have helped researchers pinpoint an area of the brain key to one's willingness to make risky decisions.

Genomic dark matter activity connects Parkinson's and psychiatric diseases

Using a new technique known as laser-capture RNA seq, that involves cutting out dopamine neurons from a human brain section with a laser, investigators have cataloged more than 70,000 novel elements active in these brain cells.

Full, but still feasting: Mouse study reveals how urge to eat overpowers a signal to stop

A new study explores the mystery of what drives eating past the point of fullness, at the most basic level in the brain. It shows that two tiny clusters of cells battle for control of feeding behavior -- and the[…]

Nerve cells in the human brain can 'count'

How do we know if we're looking at three apples or four? Researchers were able to demonstrate that some brain cells fire mainly for quantities of three, others for quantities of four and others for other quantities. A similar effect[…]

In depression the brain region for stress control is larger

Although depression is one of the leading psychiatric disorders, its cause remains unclear. A recent study found that those affected by depressive disorder have a larger hypothalamus compared to their healthy counterparts. This could explain why many sufferers show increased[…]

Fish-rich diets in pregnancy may boost babies' brain development

Women could enhance the development of their unborn child's eyesight and brain function by regularly eating fatty fish during pregnancy. This is the suggestion from a small-scale study. The research supports previous findings that show how important a prospective mother's[…]

Analysis of sea squirt embryo reveals key molecules in dopaminergic neuron differentiation

Researchers have used a novel approach for analyzing the central nervous system of a proto-vertebrate to identify a regulatory cocktail that induces the creation of dopaminergic neurons/coronet cells, a primitive version of the hypothalamus. The findings shed more light on[…]

American girls read and write better than boys

As early as the fourth grade, girls perform better than boys on standardized tests in reading and writing, and as they get older that achievement gap widens even more.

Discovery could explain failed clinical trials for Alzheimer's, and provide a solution

A vicious feedback loop underlying brain degeneration in Alzheimer's disease may explain why so many drug trials have failed, according to researchers. Their study also identifies a clinically approved drug which breaks the vicious cycle and protects against memory-loss in[…]

Zombie cells found in brains of mice prior to cognitive loss

Zombie cells are the ones that can't die but are equally unable to perform the functions of a normal cell. These zombie, or senescent, cells are implicated in a number of age-related diseases. Researchers have now expanded that list.

New insight into aging

Researchers examined the effects of aging on neuroplasticity in the primary auditory cortex, the part of the brain that processes auditory information. Neuroplasticity refers to the brain's ability to modify its connections and function in response to environmental demands, an[…]

New insights into the way the brain combines memories to solve problems

Current theories do not easily explain how people can use their episodic memories to arrive at novel insights. New research provides a window into the way the human brain connects individual episodic memories to solve problems.
