11:54 PM | How to Look for Pine Marten
The pine marten (Martes martes) is one of Ireland’s most beautiful but elusive mammals. It is notoriously difficult to see as it tends to be mostly nocturnal, and is a naturally shy animal. It is about the size of a … Continue reading →

6:18 PM | Sometimes choices are not thought out
In some competitive situations animals can produce random behavior rather than behavior based on prior experience. The anterior cingulate cortex is where strategies based on models of reality and history are generated; switching to random behavior is done by inputs to this part of the brain from the locus coeruleus. This was reported in a […]

12:37 PM | The Memory Fades, The Emotion Remains
People with Alzheimer’s disease can experience severe memory impairments.However, according to a new study, the emotions associated with events can persist long after the events themselves have been forgotten: Feelings Without Memory in Alzheimer Disease In their paper, the researchers, University of Iowa neurologists Edmarie Guzman-Velez and colleagues, showed volunteers a series of emotional video […]The post The Memory Fades, The Emotion Remains appeared first on Neuroskeptic.

7:50 AM | Yes, people with autism do have headaches
I don't mean to be haughty but a sentence included in the paper by Victorio [1] led to the title of today's very quick post. Based on a chart review of patients diagnosed with an autism spectrum disorder (ASD) attending a neurology clinic, the author concluded that "ASD patients, despite being known to have indifference to pain, can experience headaches".Pain is something which has cropped up quite a bit in the autism research arena and has appeared more than once on this blog (see here and see […]

2:30 PM | Walking Really Is Just Falling and Catching Yourself
The flailing of a gymnast who’s missed a step on the balance beam might not be far off from what the rest of us experience every day. Each step we take is really a tiny fall, a mathematical model suggests. The random-looking variation in our footfalls is actually a series of corrections. Our strides are […]The post Walking Really Is Just Falling and Catching Yourself appeared first on Inkfish.

Why do we age? It’s more than just a philosophical question; it’s a puzzle that has frustrated scientists for decades. Currently, the most accepted hypothesis is that aging is the result of accumulated damage to our cells during our lifetime. “Accumulated damage” encompasses a variety of things that can go wrong, including DNA mutations, problems […]

11:51 AM | Anthropomorphic Neuroscience Driven by Researchers with Large TPJs
For immediate release — SEPTEMBER 26, 2014Research from the UCL lab of Professor Geraint Rees has proven that the recent craze for suggesting that rats have “regrets” or show “disappointment” is solely due to the size of the left temporal-parietal junction (TPJ) in the human authors of those papers (Cullen et al., 2014). This startling breakthrough was part of a larger effort to associate every known personality trait, political attitude, and individual difference […]

7:00 AM | Eye contact makes us more aware of our own bodies
If you've ever felt acutely self conscious upon making eye contact with another person, a new study may help you understand why. Matias Baltazar and his colleagues have found that making eye contact activates people's awareness of their own bodies. That feeling of self consciousness induced by mutual gaze might be based in part on the fact that your brain is suddenly more attuned to your body.The researchers presented 32 participants with a series of positive and negative images on a computer […]
