Neurons eat glutamate to stay alive

Subjects eat food from a plate placed on a scale connected to a computer that records the weight loss of the plate during the meal. Feedback on the computer screen allows the subject to adapt her/his eating behavior to reference curves thus normalizing body...

We describe the combination of focal UV-induced photo-activation of neuro-active compounds with whole-cell patch-clamp and multi-photon imaging of intracellular sodium transients in dendrites and spines of hippocampal neurons in acute tissue slices of the mouse brain.

In this article we introduce fast micro-iontophoresis of neurotransmitters as a technique to investigate integration of postsynaptic signals with high spatial and temporal...

This video demonstrates evaluating glutamate release and clearance at single corticostriatal synapses in a mouse brain slice. Electrical stimulation facilitates glutamate release at the synapse. The released glutamate alters sensor protein's fluorescence, which decays over time, indicating release and clearance...

This video demonstrates an antibody-feeding approach to study the trafficking of glutamate receptors in primary hippocampal neuronal cultures. This approach allows the observation of receptor populations at both the plasma and internal membranes. Discrimination between these subsets is achieved by labeling the receptors before and after membrane permeabilization, using the same primary antibody but secondary antibodies conjugated to different...

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...
