Nerve cells are not just nerve cells. Depending on how finely we distinguish, there are several hundred to several thousand different types of nerve cell in the human brain according to the latest ...

The retina is often referred to as an "outpost of the brain"—after all, important steps in visual signal processing do not take place in the cerebrum, but in the nerve cells in the eye. When light ...

The processing of optical information in the retina of the eye, where the light-sensitive photoreceptors and the first nerve cells are located, is one of the most energy-intensive processes in the ...

Most human nerve cells last a lifetime without renewal. A trait echoed within the cells' components, some enduring as long as the organism itself. Most human nerve cells last a lifetime without ...

Obesity is a global health problem that affects many people. In recent years, very promising anti-obesity drugs have been developed. Despite these successes, there are patients who do not respond to ...

Millions of neurons branch throughout our bodies, keeping them in close communication with our brains. This peripheral network begins to take shape long before birth, as the cells of a growing embryo ...

Unlike the brain and spinal cord, peripheral nerve cells, whose long extensions reach the skin and internal organs, are capable of regenerating after injury. This is why injuries to the central ...

A tickly itch, a painful scratch, or the feeling of a refreshing breeze—the skin is teaming with nerve endings that drive these sensations. Scientists are getting into the epidermis to explore how ...

Early nerve commitment: Scientists found sensory and sympathetic ganglia cells decide their roles before leaving the neural tube, overturning long-held biological assumptions. Genetic barcode method: ...

Diabetes affects millions worldwide, causing both nerve and metabolic complications. A recent study suggests that diabetic nerve damage may also lead to impaired bone health. Using a mouse model of ...

Cancer cells steal energy-generating parts from nerve cells to fuel their spread to distant sites, a discovery that could improve treatments against the deadliest tumours. “This is the first time that ...
