Sleep and aging: Two sides of one coin?

A link has been identified between oxidative stress, which has previously been linked to aging and neurodegeneration, and sleep. Oxidative stress activates neurons that control sleep function. The findings could help in the development of treatments for sleep disorders.

Artificial Intelligence Can Predict Premature Death

Artificial Intelligence Can Predict Premature Death

Machine learning significantly improves the accuracy of predicting premature deaths, from all causes, in a middle-aged population compared with more traditional models.

They found this AI system was very accurate in its predictions and performed better than the current standard approach to prediction developed by human experts. The study is published by PLOS ONE in a special collections edition of “Machine Learning in Health and Biomedicine”.

The team used health data from just over half a million people aged between 40 and 69 recruited to the UK Biobank between 2006 and 2010 and followed up until 2016.

Brains of 3 People Have Been Successfully Connected, Enabling Them to Share Thoughts

I said: "The interface between brains is getting better in the last 5 years. It was in the beginning question-answer interface linking two brains, then communication, now it's way better, full communication, sharing thoughts and ideas, and it's linking three brains at the same time. Awesome!"

Not So Sweet? This Is What Happens to the Brain When You Give Up Sugar for Lent

In neuroscience, food is something we call a “natural reward.” In order for us to survive as a species, things like eating, having sex and nurturing others must be pleasurable to the brain so that these behaviours are reinforced and repeated.

More Serotonin, Less Motivation? It Depends on the Circumstances

A new study in mice shows that increasing serotonin, one of the major mediators of brain communication, affects motivation - but only in certain circumstances. Furthermore, the study revealed that the short and long term effects of increased serotonin levels are opposed - a completely unforeseen property of this neurotransmitter's functional system.

How the Hippocampus Influences Future Thinking

How the Hippocampus Influences Future Thinking

Over the past decade, researchers have learned that the hippocampus--historically known for its role in forming memories--is involved in much more than just remembering the past; it plays an important role in imagining events in the future. Yet, scientists still do not know precisely how the hippocampus contributes to episodic imagining--until now. Researchers from Boston University School of Medicine (BUSM) have determined the role of the hippocampus in future imaging lies in the process of constructing a scene in one's mind.

Menstrual Cycle Affects Memory and Navigation Skills

“Women have sometimes reported to doctors that their memory works differently depending on which phase of the menstrual cycle they are in — even during and following pregnancy, or following menopause. This has led scientists to wonder whether estrogen and progesterone could affect memory and problem solving,” says psychology professor Wayne Brake, who co-authored the study.

Originally shared by Corina Marinescu

Neurotransmission also called synaptic transmission, is the process by which signaling molecules called neurotransmitters are released by a neuron (the presynaptic neuron), and bind to and activate the receptors of another neuron (the postsynaptic neuron). Neurotransmission is essential for the process of communication between two neurons.

In 1921, an Austrian scientist named Otto Loewi discovered the first neurotransmitter.  In his experiment he used two frog hearts. One heart (heart #1) was still connected to the vagus nerve. Heart #1 was placed in a chamber that was filled with saline. This chamber was connected to a second chamber that contained heart #2. So, fluid from chamber #1 was allowed to flow into chamber #2.

Electrical stimulation of the vagus nerve (which was attached to heart #1) caused heart #1 to slow down. Loewi also observed that after a delay, heart #2 also slowed down. From this experiment, Loewi hypothesized that electrical stimulation of the vagus nerve released a chemical into the fluid of chamber #1 that flowed into chamber #2. He called this chemical "Vagusstoff". We now know this chemical as the neurotransmitter called acetylcholine.

One Area of Brain Sees Familiar Words as Pictures, Another Sounds Out Words

Skilled readers can quickly recognize words when they read because the word has been placed in a visual dictionary of sorts which functions separately from an area that processes the sounds of written words, say Georgetown University Medical Center (GUMC) neuroscientists. The visual dictionary idea rebuts a common theory that our brain needs to “sound out” words each time we see them.

Changing Our Understanding of Consciousness

Changing Our Understanding of Consciousness

Measuring and defining consciousness has been an ongoing challenge for neuroscientists, philosophers and psychologists for centuries. The concept of levels of consciousness is mostly theoretical, limiting the abilities of researchers to develop objective measurement and understanding of how different global states of consciousness relate to each other.
