Dendrites in the spotlight It’s been more than a century since dendrites captivated the curious minds of pioneer neuroanatomists –Ramon y Cajal and Wilhelm His being among the most notable and well-cited ones–, yet, we neuroscientists are still as fascinated as ever. With the dendrites comprising the most delicate of building blocks underlying the chaotic structure of our […]
Epilepsy’s impact is not limited to seizure events While most seizures resolve spontaneously after a few minutes, the long-term impact can be rather grim if the condition goes untreated. Significant memory and executive function deficits often ensue, taking a toll on patients’ daily lives. This is no surprise since the most common diagnosis for epilepsy involves […]
Quanta Magazine, published by Simon Foundation, runs an article on the hidden computational power of dendrites, drawing inspiration from our recent Science paper.

Half the credits ain’t fair! It’s been more than 37 years of science in the making, since Bienenstock, Cooper and Munro proposed their groundbreaking theory of synaptic plasticity to account for seemingly disparate experimental results on feature selectivity emergence in the feline visual cortex. Indeed, their plasticity rule, among a handful of others (Hebbian, STDP, […]

Dendritic morphology is a key determinant of how individual neurons acquire a unique signal processing profile. The highly branched dendritic structure that originates from the cell body, explores the surrounding 3D space in a fractal-like manner, until it reaches a certain amount of complexity. Its shape undergoes significant alterations under various physiological or neuropathological conditions. […]
