The Curious Case of Alice in Wonderland Syndrome
Some 40 years after “Alice’s Adventures in Wonderland” was first published in 1866, accounts of hallucinations similar to those described by Lewis Carroll began to appear in the medical literature. In 1904, William Spratling, one of the first American epileptologists, published case studies of several patients for whom “everything looked bigger” just before their seizures; three years later, in 1907, the great British neurologist William Gowers also reported epilepsy patients who perceived objects to look “twice their size” during the...

People who suffer sleep deprivation become less generous, according to new research
What determines how generous a person you are? Could it be how much money you have? How kind you are? Or maybe it comes down to your values. These all seem reasonable assumptions, but a new study from Berkeley University suggests something that feels as trivial as how well you’ve slept lately can also affect how willing you are to help other people on any given day. It found sleep deprivation leads to a reduction in generosity.

Brain imaging study suggests that interactions with other cultures can reverse racial ingroup biases in empathy
A brain imaging study published in the journal Neuropsychologia has found evidence that experiences with other cultures might reverse racial ingroup biases in empathy. The findings revealed that White students who had spent extended time in China showed stronger neural responses to pain expressions on Asian faces compared to White faces.

Scientists discover first substance that has memory like human brains
Scientists in Switzerland have discovered that a compound used in electronics is capable of “remembering” previous external stimuli in a similar way to neurons in the human brain. Mohammad Samizadeh Nikoo, a PhD student in electrical engineering at Polytechnic University of Lausanne’s POWERlab, made the chance discovery while conducting research on vanadium dioxide (VO2).

Scientists Finally Provide Relief For Depression By Locating Exact Target for Deep Brain Stimulation
Although it was a small study on 10 patients, researchers at the University of Texas Health–Houston were able to achieve something long out of reach, locating the G-spot where brain stimulators can make a real difference for depression patients.

This Artificial Neuron Uses Dopamine to Communicate With Brain Cells
The translucent chip attached to the mouse’s leg looked nothing like a neuron. Dotted with a series of sensors and channels and smaller than a human finger, it looked—and flexed—like a Band-Aid. Yet when doused with dopamine, the chip worked its magic. The mouse’s leg began to twitch and stretch. Depending on the dose of dopamine, the chip controlled the limb like a marionette.

Neuroimaging study finds people who exercise more display an elevated brain response to reward
New research published in the journal Biological Psychology revealed that people who exercise more show increased brain activity when receiving an unexpected reward, specifically in the right medial orbitofrontal cortex. These findings may suggest that regular exercise alters the reward-circuit function, potentially reinforcing exercise behavior.

Our brain is a prediction machine that is always active | Max Planck Institute
This is in line with a recent theory on how our brain works: it is a prediction machine, which continuously compares sensory information that we pick up (such as images, sounds and language) with internal predictions.

Scientists Reveal Which Brain Regions Regulate Movement
Movement is much more complicated than you might think. Any one activity, whether it's opening your mouth to speak or running a marathon, involves complicated interactions in our brains. This complexity means that there’s still much about movement that scientists struggle to understand.
