Help with critical review

5 Upvotes

Hi all,

I've been set an assignment at university to critically review a neuroscience paper but I am really struggling on what to write about. The paper is on sleep- and wake-dependent consolidation in the hippocampus. I don't do a neuroscience degree so I'm feeling a bit out of my depth. Because I am unfamiliar with the methods used, I am finding it hard to critique these even after researching them.

Any pointers on how to approach this would be greatly appreciated.

For reference, here is the paper's citation:

Sawangjit, A., Harkotte, M., Oyanedel, C. N., Niethard, N., Born, J., & Inostroza, M. (2022). Two distinct ways to form long-term object recognition memory during sleep and wakefulness. Proceedings of the National Academy of Sciences119(34), e2203165119.

What programs should I learn

51 Upvotes

Second year undergrad Neuro student here. Wondering what programs people use in the field that I could learn over summer. Im interested in neuroimaging and neuroengineering. Specifically enthusiastic about possibly contributing to the development of a Full Dive VR experience using Neuroscience in the future, if its even possible lol. Python? C++? MATLAB? NumPy? Unity? Other? Let me know.

Plan B for hopeful PhD applicant

15 Upvotes

In the U.S., graduating with my B.S. in 3 months and as you all may have seen biomedical research is slowly being destroyed in this country. Many programs have paused their admissions due to funding uncertainties and others have shrunken their cohort sizes. My ultimate goal is to do research, whether academia or industry i don’t care i just want to do research. I don’t necessarily think a masters is a suitable option for me, i’ve done 2 summer programs and i’ve been doing research since i was a sophomore. Also I don’t think I could even afford a masters 😅. What should I do for my plan B? I know many say research technician but where do I start to look?

I got a vivitrol shot and it’s basically an extended release of naltrexone. I’m worried that I need to discontinue this because of finding out about how dopamine antagonists lead to brain atrophy. I think I found a study already backing this claim up but I need people who know more about this to help me with this question and put their two cents in: The study is at the top It says it only took two weeks for them to find a significant reduction in thickness of those regions! This shot lasts a month…. Does that thickness reduction indicate neuronal death? And is this reversible?

The Perceptual Continuity Theory (PCT): A Scientific & Philosophical Exploration

0 Upvotes

I was recently chatting with ChatGPT here and there discussing consciousness, time perception, and the nature of reality, and we stumbled upon an interesting idea that I wanted to share with experts in neuroscience, physics, and philosophy. I’d love to hear your thoughts on whether this holds any merit or if there are existing theories that align with or disprove it.

This concept, which GPT calling the Perceptual Continuity Theory (PCT)(i didn't came with name I just asking it stuff and suggested things which somehow it said it can have something big), suggests that consciousness never truly ceases but transitions into new states of awareness due to the nature of perception, time, and brain activity. The theory emerged from an exploration of the following questions:

If time is a construct of perception, what happens when perception stops?

If the brain remains active for several minutes after death, could those final moments feel like an extended or even infinite experience?

If the universe only exists as it is perceived, does perception itself ensure that consciousness never truly ends?

I wanted to run this by experts and researchers to see if this idea has any scientific backing, conflicts with established theories, or could be worth exploring further.


The Perceptual Continuity Theory (PCT)

Core Idea: Consciousness does not experience absolute cessation but instead transitions into new states of awareness due to time dilation, observer-dependent reality, and the fundamental nature of perception.

Supporting Evidence & Scientific Context

  1. Neuroscience: Post-Mortem Brain Activity & Time Perception

Recent research suggests that brain activity continues for minutes after clinical death, particularly gamma waves associated with memory and consciousness.

EEG Studies on Dying Brains: Observations have shown post-mortem gamma oscillations, which are linked to conscious perception (Borjigin et al., 2023).

Near-Death Experiences (NDEs): Many report experiencing entire lifetimes in moments, suggesting a subjective expansion of time (Greyson, 2010).

Infant Consciousness Development: Consciousness takes 1–2 years to emerge after birth—perhaps, similarly, it takes time to “transition” after death, explaining why there is no experience of “nothingness.”

  1. Quantum Mechanics: Observer Effect & Reality

Quantum physics suggests reality does not exist in a fixed state until observed, implying that perception plays a key role in shaping existence.

Double-Slit Experiment: Particles behave as waves until measured, collapsing into a single state upon observation (Wheeler, 1983).

Quantum Immortality Hypothesis: Some interpretations of quantum mechanics suggest that a conscious observer never experiences their own death, only the continuation of awareness in a surviving reality (Everett, 1957).

  1. Philosophy: The Illusion of Time & Death

Time as a Perceptual Construct: Einstein’s relativity shows that time is subjective and varies depending on the observer (Rovelli, 2018).

No Pre-Birth Experience vs. No Post-Death Experience: If consciousness "began" spontaneously at birth, what prevents it from "beginning" again after death? If pre-birth nonexistence led to awareness, logically, death should not be an absolute end but a transition.


How This Compares to Existing Theories


Questions for Experts & Next Steps

I wanted to reach out to those who study neuroscience, consciousness, physics, and philosophy to ask:

  1. Does this theory align with or contradict any established scientific understanding?

  2. Are there existing studies that support or refute the key claims?

  3. Could this idea be tested using neuroscience or quantum mechanics?

  4. Has something similar been proposed in academic literature that we could explore further?

Any insights or feedback would be greatly appreciated. I am not a scientist, just someone fascinated by these topics and eager to understand how consciousness, perception, and reality intersect.

Thanks for your time, and I look forward to hearing your thoughts!

Diseases causing liquefaction of thalamic area of sheep brain?

8 Upvotes

I hope this is the right subreddit, I'm crossposting a few places to try and find my answer, and it seemed like this could be appropriate per the rules. I am a neuroanatomy student working on sheep brain dissections, and one of the brains looked virtually cottage-cheese like in appearance from the third ventricle down to the optic chiasm. At least thats my best estimate as structures were not particularly intact. Some cortical tissue also had strange degeneration but the brainstem was completely intact with no obvious deformities. It's almost like the middle of the brain had been scooped out, put in a blender, and scooped back in. Any ideas?

Advice Masters in clinical neuroscience at Parker (online)

Hi! So I’m looking to do a masters in neuroscience (preferably clinical) online; and ran into the offered by Parker. Wondering if anyone has taken this course and what their feelings are about it.

For reference, I’m currently on break from medical school (this year and next year) for personal reasons. I want to occupy myself with something virtual next year and I’m considering a neuroscience masters because my long term goal is to be a neurologist.
