Scientists identify neurons involved in correcting errors during spatial navigation

Posted by in categories: mapping, neuroscience

During routine navigation in daily life, our brains use spatial mapping and memory to guide us from point A to point B. Just as routine is making a mistake in navigation that requires a course correction.

Now, researchers at Harvard Medical School have identified a specific group of neurons in a region involved in that undergo bursts of activity when running a maze veer off course and correct their error.

A brain implant changed her life. Then it was removed against her will

And the right to freedom of thought enshrined in the Universal Declaration of Human Rights is similarly open to interpretation. It was historically put in place to protect freedoms surrounding beliefs, religion, and speech. But that could change, says Ienca. “Rights are not static entities,” he says.

He is among the ethicists and legal scholars investigating the importance of “neuro rights”—the subset of human rights concerned with the protection of the human brain and mind. Some are currently exploring whether neuro rights could be recognized within established human rights, or whether we need new laws.


Her case highlights why we need to enshrine neuro rights in law.

Tech that aims to read your mind and probe your memories is already here

In recent years, we’ve seen neurotechnologies move from research labs to real-world use. Schools have used some devices to monitor the brain activity of children to tell when they are paying attention. Police forces are using others to work out whether someone is guilty of a crime. And employers use them to keep workers awake and productive.

These technologies hold the remarkable promise of giving us all-new insight into our own minds. But our brain data is precious, and letting it fall into the wrong hands could be dangerous, Farahany argues in her new book, The Battle for Your Brain. I chatted with her about some of her concerns.

Cracking consciousness will never be easy but we are making strides

Treating Alzheimer’s Very Early Offers Better Hope of Slowing Decline, Study Finds

A trial of donanemab, an experimental drug, found it modestly slowed the worsening of memory and thinking and worked better in patients at earlier stages and those under 75.

Study sheds light on where conscious experience resides in brain

Posted by in categories: food, neuroscience

More than a quarter of all stroke victims develop a bizarre disorder—they lose conscious awareness of half of all that their eyes perceive.

After a stroke in the brain’s right half, for example, a person might eat only what’s on the right side of the plate because they’re unaware of the other half. The person may see only the right half of a photo and ignore a person on their left side.

Surprisingly, though, such stroke victims can emotionally react to the entire photo or scene. Their brains seem to be taking it all in, but these people are consciously aware of only half the world.

Neutral Monism and the Scientific Study of Consciousness (William Seager)

Posted by in category: neuroscience

Abstract: A scientific theory of consciousness could be merely descriptive, nothing more than a kind of empirical, statistical phenomenology. We already have a lot of data which fit into this kind of modest theorizing. Better would be a theory which reveals the nature of consciousness. Here a famous gap looms between any such theory of consciousness and a theory of the conscious brain, neither of which are actually in our possession. The gap is so serious and so immense that it has led to remarkable responses, such as the illusionist view that consciousness does not exist. I think the gap suggests there are lurking assumptions about the nature of both consciousness and matter which are fundamentally at odds with one another. A ‘neutral monist’ view may be able to avoid these assumptions to find a place in nature for consciousness and scientific theorizing about it.

Regulator says found no animal welfare breaches at Musk firm beyond 2019 incident

USDA found Neuralink to be in compliance with animal safety and welfare standards after an isolated incident of using an unapproved sealant to close a monkey’s skull in a surgery triggered an investigation. FDA granted a request to begin testing it’s implant device in humans.


July 19 (Reuters) — The head of the U.S. agency responsible for animal welfare has told lawmakers that it did not find any violations of animal research rules at Elon Musk’s Neuralink beyond a 2019 incident the brain implant company had already reported.

Officials with the Department of Agriculture (USDA) conducted a “focused” inspection in response to a complaint about the company’s handling of animal experiments, but identified no compliance breaches, the agency’s secretary Thomas Vilsack wrote to Congressman Earl Blumenauer in a July 14 letter reviewed by Reuters.

Understanding Causes of Devastating Neurodegenerative Condition Affecting Children

Posted by in categories: biotech/medical, genetics, neuroscience

A common theme among parents and family members caring for a child with the rare Batten disease is “love, hope, cure.” While inspiring levels of love and hope are found among these amazing families, a cure has been more elusive. One reason is rooted in the need for more basic research. Although researchers have identified an altered gene underlying Batten disease, they’ve had difficulty pinpointing where and how the gene’s abnormal protein product malfunctions, especially in cells within the nervous system.

Now, this investment in more basic research has paid off. In a paper just published in the journal Nature Communications, an international research team pinpointed where and how a key cellular process breaks down in the nervous system to cause Batten disease, sometimes referred to as CLN3 disease [1]. While there’s still a long way to go in learning exactly how to overcome the cellular malfunction, the findings mark an important step forward toward developing targeted treatments for Batten disease and progress in the quest for a cure.

The research also offers yet another excellent example of how studying rare diseases helps to advance our fundamental understanding of human biology. It shows that helping those touched by Batten disease can shed a brighter light on basic cellular processes that drive other diseases, rare and common.
