Knowledge concept recognition in the learning brain via fMRI classification

Frontiers in Neuroscience, Journal Year: 2025, Volume and Issue: 19

Published: March 21, 2025

Knowledge concept recognition (KCR) aims to identify the concepts learned in brain, which has been a longstanding area of interest for learning science and education. While many studies have investigated object using brain fMRIs, there are limited research on identifying specific knowledge points within classroom. In this paper, we propose recognize computer by classifying fMRIs taken when students concepts. More specifically, study made attempts two representation strategies, i.e., voxel time difference. Based representations, evaluated traditional classifiers combination CNN LSTM KCR. Experiments conducted public dataset collected from 25 teachers course. The evaluations fMRI segments show that used all can attain good performance time-difference representation, where CNN-LSTM model reaches highest accuracy. This contributes understanding human supports development personalized learning.

Human single-neuron activity is modulated by intracranial theta burst stimulation of the basolateral amygdala

Published: April 11, 2025

Direct electrical stimulation of the human brain has been used for numerous clinical and scientific applications. Previously, we demonstrated that intracranial theta burst (TBS) basolateral amygdala (BLA) can enhance declarative memory, likely by modulating hippocampal-dependent memory consolidation. At present, however, little is known about how affects activity at microscale. In this study, recorded EEG data from a cohort patients with medically refractory epilepsy as they completed visual recognition task. During task, brief trains TBS were delivered to BLA. Using simultaneous microelectrode recordings, isolated neurons in hippocampus, amygdala, orbitofrontal cortex, anterior cingulate cortex tested whether enhanced or suppressed firing rates. Additionally, characterized properties modulated neurons, patterns rate coactivity, extent which modulation affected task performance. We observed subset (∼30%) whose was TBS, exhibiting highly heterogeneous responses respect onset latency, duration, direction effect. Notably, location baseline predicted most susceptible modulation, although impact neuronal on remains unclear. These findings advance our limited understanding focal fields influence single-cell level motivate future neuromodulatory therapies aim recapitulate specific implicated cognition memory.

A shared code for perceiving and imagining objects in human ventral temporal cortex

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 6, 2024

Abstract Mental imagery is a remarkable phenomenon that allows us to remember previous experiences and imagine new ones. Animal studies have yielded rich insight into mechanisms for visual perception, but the neural remain poorly understood. Here, we first determined ∼80% of visually responsive single neurons in human ventral temporal cortex (VTC) used distributed axis code represent objects. We then reconstruct objects generate maximally effective synthetic stimuli. Finally, recorded responses from same population while subjects imagined specific found ∼40% axis-tuned VTC recapitulated code. Our findings reveal supported by reactivation involved providing neuron evidence existence generative model VTC. One Sentence Summary Single use feature axes encode objects, reactivates this

Hidden state inference requires abstract contextual representations in the ventral hippocampus

Published: Nov. 21, 2024

The ability to use subjective, latent contextual representations influence decision-making is crucial for everyday life. hippocampus hypothesized bind together otherwise abstract combinations of stimuli represent such contexts, support the process hidden state inference. Yet evidence a role in inference remains limited. We found that ventral required mice perform during two-armed bandit task. Hippocampal neurons differentiate two contexts this strategy manner similar differentiation spatial locations, and their activity essential appropriate dopamine dynamics. These findings offer insight into how information used optimize decisions, they emphasize key
