The results suggest that breathing is orchestrated by three—rather than two—excitatory circuits in the medulla.

This third excitatory network helps to regulate postinspiration.

The UCLA neurobiologist uses computational modeling, in vitro electrophysiology, and human psychophysics experiments to explore how neurons and the brain as a whole perceive and respond to time.

With light, researchers can coax a group of neurons in the visual cortices of living mice to fire in concert.

Surprisingly small sections of brain, and even neuronal and glial networks in a dish, display many electrical indicators of sleep.

Sleep-like patterns of neural activity are apparent not just at the level of the whole brain, but also in isolated neural circuits.

Scientists engineer a feedback loop to fine-tune neuron activity with optogenetics.

Eve Marder’s quest to understand neurotransmitter signaling is more than 40 years old and still going strong.

Scientists have defined mouse neurons responsible for excessive food consumption at an unprecedented level of detail.

Researchers have created a brain-wide map detailing links between sets of activated neurons and behaviors in fruit fly larvae.

Scientists identify hippocampal neurons involved in encoding fear in mice.

Neuroscientists are automating neural imaging and recording, allowing them to monitor increasingly large swaths of the brain in living, behaving animals.
 

New technology probes the functional unit of nervous transmission.

The brains of men contain stronger front-to-rear connections while those of women are better connected from left to right.

Researchers demonstrate the successful treatment of marijuana abuse in rats and monkeys.

Fluorescent calcium sensors in transgenic mice give a real-time readout of neuronal activity.

NIH Director Francis Collins touts the project to map neural connections in the human brain as recording the mind’s “symphony.”  

The human brain is an organized, 3D grid composed of elegant, ribbon-like fibers.

As neuroscientists look to the future of their field, they are beginning to delve into more complex factors that define our emotions and intentions.
