Aww 🥰 I got thank you notes today from the classroom I did #SkypeAScientist with last week! I enjoy the conversations with the kids so much I wouldn't notice if they didn't send a thank you-- but when they do, well, it just makes my day all over again! 💜 🧠

I told them about neuro* for ~20 min and then answered questions for 20 min, about life, the universe, and career choices. 😉

Def check it out. It is a SUCH a rewarding experience! #science #neuroscience #academia

Obeying Orders Lowers Moral Responsibility Perception in the Brain

neurosciencenews.com/moral-per

A new brain imaging study reveals that the sense of agency—our feeling of being responsible for our actions—decreases when we follow orders, regardless of whether we are civilians or military officers. Participants were asked to make moral decisions involving inflicting harm either freely or under coercion, and fMRI results showed reduce…

Isolating single cycles of neural oscillations in population spiking

doi.orgIsolating single cycles of neural oscillations in population spikingAuthor summary Neural oscillations, or rhythmic patterns of brain activity, have traditionally been studied by measuring electrical fields in the brain. In our research, we developed a novel approach that focuses directly on the activity of individual brain cells (neurons). Using machine learning, we created a tool to detect and analyze these rhythms, identifying individual cycles of brain rhythms across a wide range of timescales—from milliseconds to minutes. When we applied this method to recordings from mouse brains, we uncovered several noteworthy findings. First, we discovered that sensory information is processed in the brain as discrete packets of activity, rather than as a continuous stream. We also found that different brain regions synchronize their activity through these rhythms, with specific timing delays that depend on the rhythm’s speed. Moreover, we found that the ultra-slow rhythms in brain activity are linked to behavioral cues like changes in pupil size and facial movements, indicating that these rhythms may reflect shifts in the animal’s internal state. Our work sheds light on how the brain processes information and coordinates activity across its regions. It also introduces a powerful new tool exploring the fundamental mechanisms underlying brain function.

Self-Powered Synapse Brings Human-Like Vision to AI Devices

neurosciencenews.com/ai-synaps

Researchers have developed a self-powered artificial synapse capable of color recognition with near-human precision. Unlike traditional systems that demand external energy and massive data processing, this device mimics biological vision and generates its own electricity using solar cells. …

Why Some Individuals Adapt to Fear Faster Than Others

neurosciencenews.com/fear-adap

A new study has uncovered the brain circuits responsible for individual differences in how animals adapt to repeated visual threats. Using advanced neural recording and manipulation tools, researchers identified two distinct pathways in the brain that drive either persistent escape or rapid habituation in mice. …

SSRIs Restore Brain Function in Alzheimer’s

neurosciencenews.com/ssris-alz

A new study suggests that SSRIs, commonly prescribed antidepressants, may reduce biological markers of Alzheimer’s disease. In a cohort of 191 individuals, AD patients on SSRIs had lower levels of plasma phosphorylated tau-181, a key indicator of disease severity. …

I wrote an article earlier in the week arguing that we need to give junior researchers more independence earlier, and this should be our focus, not moonshot mega projects led by senior researchers.

I was surprised how much agreement I'm seeing.

So next question: how do we do this?

FROs are an interesting idea but I'm worried about relying on private capital.

Can public funding mechanisms do this? What are the obstacles? How did we get to a world where scientists are gaining independence only in their forties? And how can we shift this earlier?
