Brain Circuits for Spatial Memory and Navigation Identified

Researchers have identified two neural circuits in the retrosplenial cortex (RSC) that are critical for spatial navigation and memory storage. The M2-projecting pathway links spatial thought to action, while the AD-projecting pathway supports location-specific memory.

New Molecule Offers Hope for Parkinson’s by Outperforming L-Dopa

A new study has discovered that ophthalmic acid, a molecule in the brain, acts like a neurotransmitter to regulate motor function, similar to dopamine. In Parkinson’s mouse models, this molecule improved movement for over 20 hours—far longer than the effects of the current treatment, L-dopa.

Eye-Opening Insights Into Human and Insect Vision

Researchers unveiled significant findings on the production of 11-cis-retinal, a molecule crucial for vision in both humans and insects. By studying the NinaB protein in insects and comparing it to the human RPE65 protein, both essential for synthesizing 11-cis-retinal, the team discovered key differences in their operational mechanisms despite their structural similarities.

Getting the Skinny on Cannabis Use: The Effect of Cannabis on Weight and Metabolism

Researchers shed light on the enigma of cannabis users tending to be leaner and less diabetes-prone despite appetite stimulation. The study shows that cannabis exposure during adolescence disrupts energy balance and adipose organ (fat storage) homeostasis.

Alzheimer’s Pathology Found in Superagers With Superior Cognition

A new study found people who are 90+ and have superior cognitive skills have similar levels of brain pathology as Alzheimer's patients. However, they also have less brain pathology of other neurodegenerative diseases. The researchers are now looking at how lifestyle habits and health conditions are associated with superior cognition in individuals who are 90+.
