A new study shows a complex set of overlapping neuronal circuits works in concert to drive temperature preferences in the fruit fly Drosophila by affecting a single target, a heavy bundle of neurons within the fly brain known as the mushroom body. These nerve bundles play critical roles in learning and memory.
Researchers discover a population of cells, called tanycytes, are capable of generating new appetite regulating neurons in the brains of both young and adult rodents. The discovery could offer new avenues for tackling obesity.
Researchers discover presenilin, a protein associated with Alzheimer's disease, controls the speed at which materials move through brain cells. Defects in presenilin could lead to neuronal blockages with amyloid plaques, commonly associated with this neurodegenerative disorder.
Researchers find a fruit fly's salty taste sensation strategy could apply to other animals, even humans.
New research identifies a pair of neurons which control the feeding behavior in Drosophila fruit flies. The discovery could help scientists better understand how the brain uses stimuli and memory to produce classically conditioned responses.
Researchers have mapped the activity of brain cells in the mushroom body of flies conditioned to have Pavlovian behavioral responses to different odors. The findings suggest the activity of as few as 25 neurons are required to be able to distinguish between different odors.
Researchers develop a flexible carbon-nanotube 'harpoon' to study individual brain neurons. The 'brain harpoon' harnesses the electromechanical properties of carbon nanotubes to capture the electrical signals generated by single neurons.
A new study points to a newly discovered system in which the brain removed waste as a potential new tool to treat neurodegenerative disorders.
Inflammation in the brain prevents cells from accessing the iron they need in order to perform a critical role in neurodevelopment.
Researchers from Allen Institute have released a publicly available database of live human brain cells. The data is comprised of samples taken from neurosurgery patients and includes over 300 living cortical neurons of different types.
Study identifies rare brain cell types that are unique to male mice, and others that are unique to females. The cells were discovered in the hypothalamus, a region of the brain that governs both aggression and mating behaviors.
