Predictive Processing: the role of confidence and precision
by Sergio Graziosi in Writing my own user manual - Sergio Graziosi's Blog
This is the second post in a series inspired by Andy Clark’s book “Surfing Uncertainty“. In the previous post I’ve mentioned that an important concept in the Predictive Processing (PP) framework is the role of confidence. Confidence (in a prediction)…Read more ›... Read more »

Wait, let me google it. On the fall (and rise?) of human memory.
by gdw in FictionalFieldwork
Ruins of a memory palace Once upon a time, there were no computers. And yet, even in the ancient days when writing was not widespread, people told gigantic tales or recited poems of epic proportions. Often more than once. Admittedly, they probably changed a bit along the way, but still the plot remained intact. How […]... Read more »

Exercise Puts Me To Sleep – You Too
by Mark Lasbury in As Many Exceptions As Rules
A New Year’s resolution to exercise could also help you sleep. But how? It wears you out and reduces stress, but there is much more. Exercise manipulates the temperature of the body by messing with your brain and modulates immune cytokine levels. It’s true… your immune system controls sleep cycles!... Read more »

Exercise, be smarter, save time
by Patrick Mineault in xcorr
The majority of mortals complain bitterly of the spitefulness of Nature, because we are born for a brief span of life […]. It is not that we have a short space of time, but that we waste much of it. Life is long enough, and it has been given in sufficiently generous measure to allow the […]... Read more »

The ‘Glass Brain’ shows neuronal firing in real-time!
by Vaibhav Jain in NEUROFANATIC
Stunning 3D ‘glass brain’ shows neurons firing off in real-time. The structure of the brain is mapped using magnetic resonance imaging (MRI). The user then wears cap covered with electrodes that measure differences in electric potential to record brain activity. This activity is revealed on-screen. The different colors represent the different frequencies of electrical energy in the brain, as […]... Read more »

New approaches to epilepsy treatment: optogenetics and DREADDs
by neurosci in Neuroscientifically Challenged
Epilepsy refers to a group of disorders that are characterized by recurrent seizures. It is a relatively common neurological condition, and is considered the most common serious (implying that there is a risk of mortality) brain disorder, affecting around 2.2 million Americans.The seizures associated with epilepsy are not homogenous; they can have a drastically different presentation depending on the patient, the part of the brain the seizure originates in, and how much of the brain the seizure ........

Using Ultrasound to Boost Brain Performance

Exercise Puts Me To Sleep – You Too
by Mark Lasbury in As Many Exceptions As Rules
A New Year’s resolution to exercise could also help you sleep. But how? Sheer exhaustion is one way and reducing stress is another, but there is much more. Research is showing that exercise can induce sleep in the anterior hypothalamus and preoptic nucleus by either manipulation the temperature of the body or by modulating cytokine levels. Studies indicate that decreased temperature after exercise stimulate the brain to inhibit wakefulness signals modulated by orexin/hypocretin. Additional........ Read more »

A new quantitative measure of consciousness: measuring the complexity of neural ripples
by Robert Seymour in NeuroFractal
It has been suggested that behavioural measures of consciousness result in an alarmingly high 43% misdiagnosis rate for Vegetative State (VS) patients – a state in which people completely lack cognitive function but still show sleep-wake cycles and often open their eyes. Could there be a more reliable neural marker? In a recent paper Casali et al., (2013) suggests that there might be. ... Read more »

Why PLOS ONE is no longer my default journal
by Juan Nunez-Iglesias in I Love Symposia!
Time-to-publication at the world’s biggest scientific journal has grown dramatically, but the nail in the coffin was its poor production policies.

“Gentlemen, we can rebuild him. We have the technology. We have the capability to make the world’s first bionic man. Steve Austin will be that man. Better than he was before. Better…stronger…faster.”
Readers of a certain age will tingle with recognition at those words, intoned over the intro to ’70s TV series “The Six Million Dollar Man“, promising the bodily reconstruction of a seriously injured astronaut.

How Schizophrenia Affects the Brain

It’s hard to fully understand a mental disease like schizophrenia without peering into the human brain.
