Brain seasonality: Bean bug neurons need biological clock gene for seasonal egg-laying
Biological clocks don't just tick for humans, they're needed by most animals. Researchers from Japan have discovered that insect neurons that promote egg-laying need a biological clock gene for a day length-dependent adaptive ...

Real-time behavioral analysis using artificial intelligence
Every behavior of an animal is based on the interaction of many nerve cells in the brain, which form a close-meshed web called a neuronal network. However, what happens in the neuronal networks during particular behaviors ...

Where did brains come from?
Charles Darwin wrote a book called "The Power of Movement in Plants" with his son Francis in which they first identified the root apex as the central command center of plants. In contrast to our own orientation with respect ...
An inner sensor of body movement revealed in zebrafish
Researchers at Karolinska Institutet have revealed a central proprioceptive organ built directly into the central nervous system that acts as an inner movement sensor. The article was recently published in the journal Neuron.

Using genetic sequencing to determine if bird and mammal brains work the same
A team of researchers from the Howard Hughes Medical Institute, the University of California–San Francisco and the University of Texas has used genetic sequencing to compare the brains of birds and mammals. They've published ...
Recovery of ovarian function in infertile mammals lacking gonadotropin release
Gonadotropins are any hormones that are released from the anterior pituitary to stimulate the gonads, or sex glands, to carry out their reproductive functions. The gonadotropin-releasing hormone (GnRH) is therefore fundamental ...

Neuron
A neuron (pronounced /ˈnjʊərɒn/ N(Y)OOR-on, also known as a neurone or nerve cell) is an excitable cell in the nervous system that processes and transmits information by electrochemical signalling. Neurons are the core components of the brain, the vertebrate spinal cord, the invertebrate ventral nerve cord, and the peripheral nerves. A number of specialized types of neurons exist: sensory neurons respond to touch, sound, light and numerous other stimuli affecting cells of the sensory organs that then send signals to the spinal cord and brain. Motor neurons receive signals from the brain and spinal cord and cause muscle contractions and affect glands. Interneurons connect neurons to other neurons within the same region of the brain or spinal cord. Neurons respond to stimuli, and communicate the presence of stimuli to the central nervous system, which processes that information and sends responses to other parts of the body for action. Neurons do not go through mitosis, and usually cannot be replaced after being destroyed, although astrocytes have been observed to turn into neurons as they are sometimes pluripotent.
