How Anesthesia Blocks Consciousness

A new study reveals insights into how general anesthesia affects consciousness and sensory perception. Using animal models, researchers found that while propofol anesthesia allows sensory information to reach the brain, it disrupts the spread of signals across the cortex.

Visual Recognition Memory: Familiarity Decoded by Brief Spikes

Decoding the brain's knack for distinguishing new from familiar is a challenge that has puzzled scientists. New research brings clarity to "visual recognition memory" (VRM), the process that ensures we prioritize what's most important in what we see.

Mice in Maze Shed New Light on Rodent Learning and Cognition

Researchers have delved deeper into mouse behavior, challenging previous assumptions about their cognitive strategies in reward-based learning tasks. While humans efficiently adopt the "win-stay, lose-shift" approach in "reversal learning" activities, mice were observed to blend this with an exploratory strategy.

The Molecular Logic Behind Neuron Diversity

Researchers uncovered how distinct neuron types in the Drosophila fruit fly differentiate their functions despite originating from a similar genetic framework. In the study, two closely related neuronal subtypes expressed more than 800 different genes (~5% of the fly genome) differently.

This shows a man's head and dots of light.

Neuron Support Squad: Perlecan Protein Key to Synaptic Durability

A new study discovered the critical role that Perlecan, a protein, plays in maintaining the structural integrity of neurons, particularly the long branches called axons. The study found that in the absence of Perlecan, axons in Drosophila fruit flies broke apart during development, leading to the death of their connections or synapses.

Cytoelectric Coupling: Electrical Fields Fine-Tune Brain Functioning

Scientists present a hypothesis dubbed "Cytoelectric Coupling" suggesting electrical fields within the brain can manipulate neuronal sub-cellular components, optimizing network stability and efficiency. They propose these fields allow neurons to tune the information processing network down to the molecular level.

Neurons Vulnerable to Alzheimer’s Identified

Researchers identified a subset of neurons in the mammillary body of the hypothalamus which are susceptible to hyperactivity and neurodegeneration. This damage often leads to memory impairment associated with Alzheimer's disease. Treating these neurons with a drug currently used in the treatment of epilepsy reverses memory impairments caused by this hyperactivity and neurodegeneration.
