This Week in Neuroscience

TWiN explains how anti-DNA antibodies present in lupus patients bind to GluN2A-containing NMDA receptors, act as positive allosteric modulators, and impair spatial memory.

TWiN explores a study of hallucination-like perception in mice which supports the idea that hallucinations arise as faulty perceptual inferences due to elevated dopamine in the striatum.

While perceptual constancy requires the brain to maintain a stable representation of sensory input, TWiN explores a study showing that odor-evoked responses in the olfactory cortex drift over periods of days to weeks.

On this episode, Vivianne gives a primer on glial cells, with the goal of thinking about the central nervous system holistically and appreciating the different cell types that contribute to its function.

Michael Nitabach joins TWiN to discuss the finding that the nematode C. elegans, which do not have eyes, can discriminate between colors to guide foraging decisions and move them away from harmful bacteria that produce a blue-pigment toxin.
