A Newfound Neuron Might Help Keep the Brain's Cells in Sync

For Vikaas Sohal, a neuroscientist at UC San Francisco, who was not involved in the work, the discovery of these cells might help the field move away from conflicts about gamma rhythms. If they really are clock-like cells, he says, then signs of their timekeeping should show up in the rhythm of the local field potential.

Lasers Highlight Ketamine's Depression-Fighting Secrets

And mice don’t have anywhere near our behavioral complexity.“It's important to recognize here the mouse doesn't really have depression per se,” says Yale psychiatrist Alex Kwan, who has studied the effects of ketamine on mouse brains.

How the Brain Links Gestures, Perception, and Meaning

How the Brain Links Gestures, Perception, and Meaning

More than a century ago, the psychologist Walter Pillsbury wrote: “There is nothing in the mind that has not been explained in terms of movement.” This concept has its modern incarnation in the mirror neuron theory, which posits that the ability to glean meaning from gesture and speech can be explained by the activation of single cells in key brain regions.

Marc Howard , a cognitive neuroscientist now at Boston University, and Karthik Shankar , who was then one of his postdoctoral students, wanted to figure out a mathematical model of time processing: a neurologically computable function for representing the past, like a mental canvas onto which the brain could paint memories and perceptions.

Monkeys With Superpower Eyes Could Help Cure Color Blindness

Monkeys With Superpower Eyes Could Help Cure Color Blindness

(It affects about 1 percent of human men and a far smaller fraction of women; the more common form of red-green colorblindness, a mutation called "deuteranopia" in the cone that senses greenish, medium-wavelength light is a little more common—like 6 percent of men.) The implication of all those likewise-envisioned brothers was that Daltonism somehow ran in families—though Darwin’s Origin of Species and the concept of evolution were still six decades in the future.

Neural Networks Need a Cookbook. Here Are the Ingredients

Neural Networks Need a Cookbook. Here Are the Ingredients

In 1989, computer scientists proved that if a neural network has only a single computational layer, but you allow that one layer to have an unlimited number of neurons, with unlimited connections between them, the network will be capable of performing any task you might ask of it.

The Genius Neuroscientist Who Might Hold the Key to True AI

The Genius Neuroscientist Who Might Hold the Key to True AI

According to the most popular modern Bayesian account, the brain is an “inference engine” that seeks to minimize “prediction error.”In 2001, Hinton left London for the University of Toronto, where he became one of the most important figures in artificial intelligence, laying the groundwork8 for much of today’s research in deep learning.8 In 2012, Hinton won the ImageNet Challenge, a competition to identify objects in a 15-million-image database built by Fei-Fei Li. ImageNet helped propel neural networks—and Hinton—to the forefront of AI.Before Hinton left, however, Friston visited his friend at the Gatsby one last time.
