Navigation brain cells in retrosplenial cortex preserved across evolution — English Level A1

Researchers find special brain cells in mice.
These cells help navigation and knowing location.
They are in the retrosplenial cortex.
Darwin called the skill dead reckoning.
The cells act like a subconscious GPS.
There are two unique neuron types.
Both types are found in mice and rats.
One type is slightly larger in rats.
People with Alzheimer’s have trouble finding home.
Scientists now check human brains for these cells.

Lab-grown brain-like tissue without animal materials

Scientists grew functional brain-like tissue using a new synthetic scaffold instead of animal‑derived coatings. The scaffold, made from PEG, supports donor brain cells and could help test drugs and reduce animal use in research.

Possible virus link to ALS-like disease found in mice

Researchers studied a mouse strain called CC023 and found that a viral infection produced lasting nerve damage and symptoms similar to ALS. The strain may help find early biomarkers and test new treatments for sporadic ALS.

Targeting a brain circuit to reduce opioid relapse

Researchers at Washington State University found that lowering activity in a specific brain connection cut heroin-seeking in a preclinical model. The study identifies a pathway between the prelimbic cortex and the paraventricular thalamus and tests two ways to reduce its activity.

Attention cycles seven to ten times per second

Scientists found that human attention shifts in a steady rhythm about seven to ten times per second. This rhythm helped early humans notice danger but can make modern people more vulnerable to phone and computer distractions.

Nasal nanomedicine clears deadly brain tumours in mice

Researchers used spherical nucleic acids given through the nose to deliver a STING-activating therapy that eradicated glioblastoma in mice and produced long-term immunity. The study appears in PNAS.
