How cool is that. Just got reminded of this paper:

"Behavioral architecture of the cortical sheet", Douglas and Martin, 2012
cell.com/current-biology/fullt

... proposing two axes across the cerebral cortex, one on time and one on space: a "Functional organisation of cortical sheet", as Figure 3 summarizes.

#neuroscience #CerebralCortex

"unfolded in plan view, the cortical sheet (cyan) is surrounded by limbic cortices (brown, e.g. cingulate cortex, insula) and their associated nuclei (red, e.g. septal nuclei, amygdala). The concept presented here is that the components of behavior are systematically distributed across this regular sheet.

Around the central sulcus (thick red horizontal line) processing relates to the direct and immediate engagement of the agent with its environment. The more anterior cortex processes potential action repertoires, plans and goals that extend forward in time, whereas the more posterior cortex processes space, which extends progressively further from the agent (and so also further into future planning time). The temporal lobe encodes objective structures such as places, objects, and faces. This lobe is greatly enlarged in primates, including humans, and is intimately related to the declarative memory functions involving the hippocampus. ... Dynamically evolving behaviors are represented schematically as graphical structures composed of ‘nodes’, the regions of active processing, and ‘edges’, which represent the axonal communication channels between active nodes. ... Multiple behaviors may evolve simultaneously (green graph, see text), while the red graph represents the various functional relations of the behavior currently being executed.

"Short-term memory errors are strongly associated with a drift in neural activity in the posterior parietal cortex", Joon Ho Choi et al. 2025 (Jong-Cheol Rah's lab).

"Using 2-photon calcium imaging in the posterior parietal cortex (PPC) of mice performing a delayed match-to-sample task, we identified a subset of PPC neurons exhibiting both directional and temporal selectivity. Contrary to the hypothesis that STM errors primarily stem from mis-encoding during the sample phase, our findings reveal that these errors are more strongly associated with a drift in neural activity during the delay period. This drift leads to a gradual divergence away from the correct representation, ultimately leading to incorrect behavioral responses."

Surprisingly, at preterm age, signals were anti-correlated (H < 0.5) but later became long-term positively autocorrelated (H > 0.5) at term; like we see in adults

L'amore è anche una questione di cervello. Scoperta nel cervello la ‘casa dell’amore’. Studio finlandese svela dove risiedono i sentimenti per figli, partner e animali. Un team di scienziati dell'università di Aalto ha indagato sei tipi di amore, ognuno dei quali illumina parti diverse del nostro cervello. Quello genitoriale sembra avere una marcia in più.
L'amore? Una questione di cervello.

🐦 Exciting News! 🐦
New research from Durham University shows how both sighted and blind people can train their brains to echolocate using sound echoes, just like bats and dolphins! 🦇🐬
Over 10 weeks, 12 blind and 14 sighted participants learned echolocation through click-based training. The results? MRI scans revealed that their brains adapted in similar ways, reorganizing the primary visual cortex to process sound echoes! 🧠🔍
This groundbreaking study proves that our brains are incredibly adaptable, no matter our sensory abilities. 🌟 This offers new hope for those with progressive vision loss, demonstrating that with practice, we can develop new ways to navigate our surroundings. 🌍✨
Kudos to the amazing researchers, Dr. Lore Thaler and Dr. Liam Norman, for leading this innovative study. Your work is truly inspiring! 👏👏
Read more about this incredible study in the journal Cerebral Cortex. 📚

@lzg my grandma suffered several strokes.
We took care of her, she lost the ability to speak for 3 or 4 months.
After a great therapist helped her, she regained speech via repeating ONE WORD that we understood thanks to tone and frequency variations.

“Cortical circuitry mediating inter-areal touch signal amplification” by Ryan et al. 2023 (Simon Peron lab). biorxiv.org/content/10.1101/20

“we ask how topographically matched subregions of primary and secondary vibrissal somatosensory cortices (vS1 and vS2) interact during whisker touch.”

And found cortical layer 2 neurons responsible for interarea synchrony.

“we identified a sparse subset of neurons in the primary visual cortex (V1) and higher visual areas that respond emergently to ICs [illusory contours]. We found that these highly selective "IC-encoders" mediate the neural representation of IC inference. Strikingly, selective activation of these neurons using two-photon holographic optogenetics was sufficient to recreate IC representation in the rest of the V1 network, in the absence of any visual stimulus.”

Switchable neural components in turtles. Perhaps not surprising but certainly extraordinary! The source paper:

"Responses of the in vitro turtle brain to visual and auditory stimuli during severe hypoxia", Ariel et al. 2023 doi.org/10.1242/jeb.244687

"North American pond turtles (Emydidae) are renowned for their ability to survive extreme hypoxia and anoxia, which enables several species to overwinter in ice-locked, anoxic freshwater ponds and bogs for months."

These qualities make turtles fantastic laboratory animals for neuroscience research:

@Javierzsm A great reminder that the activity of a neuron matters in a different way to each target neuron type because the postsynaptic site is cell-type specific. Thanks for your work!
