In the hippocampus, a critical brain region for learning and memory, new cells emerge in some people into late adulthood, ...

Researchers have pinpointed the precise pathway in the brain that suppresses pain in times of threatening situations.

Developmental Implications Many of the mechanisms during neuron pathway finding are redundant and resilient. Thus, severe aberrations must occur for major developmental abnormalities to be ...

Of all the senses, the somatosensory system is the most complex, and therefore touch, some researchers argue, is the most difficult to study. Vision and hearing, for instance, are confined to the ...

Scientists created a 3D replica of the human pain pathway using lab-grown organoids, offering insight into chronic pain, autism, and drug testing, no animals needed.

Reflex Action and Reflex Arc A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This ...

The shape of these special “receiver” structures, or neuron receptive endings (NREs), play a critical role in receiving external environmental signals. In short, the shape of the neuron-ending itself ...

To build a sensory-friendly pathway of your own, start by determining where you want it located. Go outside with a 100-foot tape measure, string, and some stakes, so you can begin to roughly mark it ...

As a single neuron connects to a web of other cells by various pathways, this milestone branches out toward many different futures of research. One path leads to the connectomes of more complex ...

When sensory neuron communication was silenced, the sympathetic nervous system kicked into gear and began converting the white fat cells into brown fat. This mechanism steps up the body’s fat ...

Yet the brain pathways responsible for gathering threatening information from the body’s sensory system and initiating the fear response are not fully understood, but new research offers some clues.
