1. Rapid Alternation Conscious Suppressed

The first story is a new bioRxiv preprint about how the primate brain represents conscious and suppressed visual images. Researchers used Neuropixels recordings across face-processing regions in inferotemporal and prefrontal cortex while one image was visible and another was suppressed with binocular flash suppression.

2. Effect Chlorogenic Acids On

The second story comes from a randomized, double-blind, placebo-controlled trial in Nutrients on chlorogenic acids and cognitive function. Thirty-eight healthy adults received either a chlorogenic-acid beverage or a placebo every day for sixteen weeks, then completed the CNS Vital Signs cognitive battery.

3. Oxidative Stress Brain Basic

The third story is a review in Antioxidants about oxidative stress in the brain during stroke. The authors describe oxidative stress as an imbalance between free-radical production and the antioxidant systems that normally remove those molecules.

Neuroscience Daily for 14 October follows 3 stories from r/neuro and r/neuroscience, moving through near-death evidence, pollution and parkinson’s, hemispheric organization.

Chapters

• 00:00:00 — Intro
• 00:00:09 — Near-Death Evidence
• 00:01:02 — Pollution and Parkinson’s
• 00:01:55 — Hemispheric Organization
• 00:02:55 — Closing

1. Near-Death Evidence

This story examines a letter to the editor in Brain Communications that challenges a proposed evolutionary link between near-death experiences and thanatosis, the defensive behavior often called playing dead. The original idea suggests that some features of near-death experiences could be remnants of an ancient survival response seen across animals.

2. Pollution and Parkinson’s

A report from The Brighter Side examines long-term air-pollution exposure and the risk of Parkinson’s disease. Researchers at the University of Cambridge reviewed 26 Parkinson’s studies, along with smaller evidence sets on multiple sclerosis and motor neurone disease.

3. Hemispheric Organization

The bioRxiv preprint examines how language and attention are organized across the brain’s hemispheres. Using brain scans and family data from 987 participants, the researchers identified right-sided, left-sided, and bilateral attention patterns that were independent of handedness and varied by sex.

Neuroscience Daily for 12 October follows 3 stories from r/neuro and r/neuroscience, moving through oral-brain link, predictive midbrain, 10% brain myth.

Chapters

• 00:00:00 — Intro
• 00:00:08 — Oral-Brain Link
• 00:01:04 — Predictive Midbrain
• 00:02:05 — 10% Brain Myth
• 00:03:15 — Closing

1. Oral-Brain Link

This story is about a Cureus review examining how gum disease might connect with Alzheimer’s and Parkinson’s disease. The review describes a possible oral-brain axis involving microbial imbalance, inflammation, immune signaling, blood-brain barrier changes, oxidative stress, and protein aggregation.

2. Predictive Midbrain

The second story examines a Nature Neuroscience study of the human superior colliculus, a small midbrain structure involved in sensory integration and action. Using high-resolution 7-Tesla fMRI in 80 people, the researchers compared responses to visual and somatosensory stimulation across the structure’s layers.

3. 10% Brain Myth

The final story is a science explainer from Oddly Clear that takes apart the 10% brain myth. The post points out that the brain is active across its systems and uses roughly a fifth of the body’s energy despite making up about two percent of body mass.
