Upgrading brain storage: Quantifying how much information our synapses can hold

Two neurons, one in full (left, light purple) and one partially out of frame (right, light blue) on top of a background of zeros and ones to symbolize the unit of bits used to quantify information storage in synapses. The neuron on the left…

Can Anxiety Relief Come at the Cost of Cognitive Health?

Can Anxiety Relief Come at the Cost of Cognitive Health?

Key points Long-term use of benzos can lead to addiction & cognitive impairments. Older people are particularly vulnerable to the impairing effects of long-term benzodiazepine use. A recent study revealed the mechanism by which benzos interfere with plasticity and cognitive abilities. Other treatments such…

Researchers demonstrate a new mechanism of neural plasticity underlying learning and memory processes

Graphical abstract. Credit: Cell Reports (2024). DOI: 10.1016/j.celrep.2024.114112 Neurons are important, but they are not everything. Indeed, it is “cartilage,” in the form of clusters of extracellular matrix molecules called chondroitin sulfates, located in the outside nerve cells, that plays a crucial role in…

Sleep resets brain connections for a few hours, but then what happens?

Sleep resets brain connections for a few hours, but then what happens?

In a study involving zebrafish, a team of scientists led by the University College London (UCL) has explored how the brain manages synaptic connections during sleep . The experts found that the brain weakens new neural connections that were forged during waking hours, but…

Debunking the 10% Brain Myth

Debunking the 10% Brain Myth

Many people believe that we only use 10% of our brains, but this idea isn’t supported by science. This article will explore where this myth came from, why it’s so appealing, and what the truth really is about our brain’s capabilities. Despite being disproven…

Revolutionary brain stimulation technique shows promise for treating brain disorders

The human brain’s adaptability to internal and external changes, known as neural plasticity, forms the foundation for understanding cognitive functions like memory and learning, as well as various neurological disorders. New research conducted by a team led by Dr. PARK Joo Min of the…
