The neural representations of a perceived image and the memory of it are almost the same. New work shows how and why they are different.
Microbe found in cat poo could be harnessed to deliver large, complex proteins across the blood–brain barrier.
As a medical scientist, he looks at how new findings will help develop new treatments to revive people now considered hopeless and restore brain damage.

Scientists propose that human consciousness evolved primarily for social survival, enabling better communication and interaction within communities, rather than just individual benefit, challenging traditional views on the evolution of subjective awareness.
Brain-computer interfaces (BCIs) can translate a person’s brainwaves into action, but these devices are vulnerable to hacking.
Researchers led by the University of California, Irvine have discovered how the TREM2 R47H genetic mutation causes certain brain areas to develop abnormal protein clumps, called beta-amyloid plaques, associated with late-onset Alzheimer’s disease. Leveraging single-cell Merfish spatial transcriptomics technology, the team was able to profile the effects of the mutation across multiple cortical and subcortical brain regions, offering first-of-their-kind insights at the single-cell level.
The study, published in Molecular Psychiatry, compared the brains of normal mice and special mouse models that undergo changes like those in humans with Alzheimer’s.
Findings revealed that the TREM2 mutation led to divergent patterns of beta-amyloid plaque accumulation in various parts of the brain involved in higher-level functions such as memory, reasoning and speech. It also affected certain cell types and their gene expression near the plaques.

Elon Musk says his startup Neuralink has implanted a brain chip into a second patient and plans to perform another eight trials later this year.
Almost half the electrodes are working… for now.
(THE CONVERSATION) Racism steals time from people’s lives – possibly because of the space it occupies in the mind.
Question Is racial discrimination associated with brain connectivity, and are alterations in deep brain functional connectivity associated with accelerated epigenetic aging?
Findings In this cohort study of 90 Black women in the US, higher self-reported racial discrimination was associated with greater resting-state functional connectivity (RSFC) between the locus coeruleus (LC) and precuneus. Significant indirect effects were observed for the association between racial discrimination frequency and DNA methylation age acceleration.
