Dopamine helps us learn to avoid bad outcomes by reinforcing behaviors that lead to better choices and discouraging those ...

Major scientific discoveries can arise from simple decisions: say, by simply looking where virtually no one else has. Such ...

Neurons—the nerve cells responsible for transmitting electrical and chemical signals throughout the body—are organized in tissue, tending to cluster together in groups according to how they function.

PASS theory explains cognition through four processes—planning, attention, simultaneous, and successive—that offer a dynamic ...

A new experiment suggests that the thalamus plays a key role in humans becoming consciously aware of stimuli their brain ...

They focused specifically on behavioral symptoms, which had not previously been investigated, and mapped the brain regions involved. They discovered that a structure in the brainstem, a part of ...

Researchers have created the largest and most detailed wiring diagram of a mammalian brain to date, by mapping cells in a ...

Functional brain imaging also showed differences in communication between the hypothalamus and regions of the brain, including those involved in motivation and reward, an apparent effect of ...

Summary: A new study has identified a brain circuit that correlates with how intensely people engage in politics, regardless of their political beliefs. Researchers examined data from 124 male ...

“The other aspect is to conduct science.” As more detailed maps of neural connections are created, spanning various species and brain regions, NEURD will be crucial for advancing the understanding of ...

Next, a second group dissected that same brain region, dividing it into layers 1/400th the width of a human hair, and took pictures of each slice. Due to the delicate nature of the structure ...

The medium spiny neurons, which are the main long-range projection neurons in this brain region, showed signs of metabolic stress, with decreased activity in mitochondrial genes that control cellular ...
