First experimental proof for brain-like computer with water and salt
Below shows a graphical representation of the synapse. The synapse consists of colloidal spheres with nano-channels between them. Credit: Utrecht University Theoretical physicists at Utrecht University, together with experimental physicists at Sogang University in South Korea, have succeeded in building an artificial synapse. This…
New brain-like transistor mimics human intelligence
Taking inspiration from the human brain, researchers have developed a new synaptic transistor capable of higher-level thinking. Designed by researchers at Northwestern University, Boston College and the Massachusetts Institute of Technology (MIT), the device simultaneously processes and stores information just like the human brain….
There’s a ‘Wave of Death’ in Every Human Brain. Scientists Are Scrambling to Stop It.
Working to Stave Off Brain’s ‘Wave of Death’Ioannis Tsotras – Getty Images Researchers studying the brain’s final moments have gained new insight into the “wave of death” that occurs before a brain’s activity fully flatlines. When neural activity stops, it doesn’t stop abruptly, but…
When do brains grow up? Research shows mouse and primate brains mature at same pace
Excitatory axon development in mouse and primate. a Cartoon depicting hypothetical models of excitatory axon development: left, axons increase their synapse frequency and/or right, axons make more branches. b, c Histograms of the number of synapses/µm and branches/µm, respectively, of excitatory axons at different…
Neuroscientists pinpoint how memories are likely to be stored in the brain
Credit: CC0 Public Domain What is the mechanism that allows our brains to incorporate new information about the world, and form memories? New work by a team of neuroscientists led by Dr. Tomás Ryan from Trinity College Dublin shows that learning occurs through the…
Neuroscientists are Tantalizingly Close to Mastering How Psychedelics Redesign Our Brains
The first-line pharmacological treatment for major depressive disorder (MDD) is antidepressant drugs known as selective serotonin reuptake inhibitors (SSRIs). However, a significant proportion of people don’t respond to these drugs. Given that major depression is a global mental health problem that is on the…
Memory Block: How Saturated Fats May Hinder Memory Formation in the Aging Brain
A new study suggests that a high-fat diet may impair memory by causing inflammatory effects and issues in cell-signaling management in the brain cells, especially as people age, but the omega-3 fatty acid DHA may help mitigate these effects. The research, focusing on microglia…
Relationship between Brain Activity and Behavior Mapped at Level of Each C. elegans Neuron
C. elegans. [Arturo Agostino] To understand the full relationship between brain activity and behavior, scientists need a way to map this relationship for all of the neurons across a whole brain, something that has so far remained an unsolved challenge. Researchers at the Picower…
Nootropics: What Nootropic Supplements Can Do for You
What Nootropic Supplements Can Do for You In today’s fast-paced world, the demand for cognitive enhancement and mental clarity is steadily increasing. Health enthusiasts are constantly seeking new means of improving focus, memory and overall cognitive function to remain competitive in both personal and…
The #1 Brain Exercise for Memory Improvement, According to Neurologists
You likely already know to brush teeth to prevent dental cavities, work out to s trengthen muscles and wear sunscreen to protect skin, you may not realize there are things you can do to keep your brain sharp . For starters, a 2019 study…
Brain networks encoding memory come together via electric fields, study finds
A) Neural field model and connections. Neural fields provided a quantitative way to describe each ensemble’s patterns of activity across simultaneously recorded sites. The same model can describe different ensembles. Each electrode occupies a position on a cortical manifold (line) Δ parameterized by the…
Old Memories Can Prime Brains to Make New Ones
Memories are shadows of the past but also flashlights for the future. Our recollections guide us through the world, tune our attention, and shape what we learn later in life. Human and animal studies have shown that memories can alter our perceptions of future…
Synaptic Secrets Revealed: Scientists Use AI To Watch Brain Connections Change
Scientists from Johns Hopkins University have harnessed artificial intelligence to visualize and track synaptic changes in live animals, aiming to enhance our understanding of brain connectivity changes in humans due to learning, aging, injury, and illness. By using machine learning, they were able to…
Battle of the Dendrites: How Neurons Compete To Cut Connections
Researchers at Kyushu University discovered the chemical pathways that regulate synaptic pruning, a crucial phase in brain development where excessive and incorrect neuronal connections are eliminated. The team found that in the presence of neurotransmitter signaling, the receiving dendrite is protected while other dendrites…
