Stimulus-specific recruitment of human amygdala neurons predicts episodic memory encoding success

The paper shows that specific amygdala neurons in humans fire more during encoding of items later remembered, predicting episodic memory success, particularly in the right amygdala.

Cellular code for mnemonic pattern separation in the human hippocampus is revealed by false memories

The paper identifies memory selective neurons in the human hippocampus that correlate with pattern separation and show behavioral relevance in episodic memory.

Criterion-selective neurons in the human medial frontal cortex track decision thresholds during memory-based decision making

The paper identifies two types of neurons in the medial frontal cortex that track decision criteria and memory strength during memory-based decision making.

Choice-driven remapping of action- and stimulus-anchored value in human single neurons

The paper records single neuron activity in human brain regions during reward tasks to show how value encoding shifts from domain-general to domain-segregated during decision-making.

Microstimulation of the human dopaminergic midbrain causally reshapes value-based decision-making and happiness

This study shows that microstimulation of the human midbrain alters decision-making and happiness by changing how losses are processed.

Autonomous error detection is enabled by conflict-dependent forward models in human medial frontal cortex

The paper identifies a mechanism in human medial frontal cortex for detecting errors without external feedback, showing preSMA encodes conflict-dependent forward models that align with error commission.

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

The paper shows that human ventral temporal cortex neurons use a distributed axis code for object perception and that imagery reactivates this code in single neurons.

Verbally specified task goals reorganize visual codes in human ventral temporal cortex via medial frontal modulation

The paper shows that verbal task instructions rapidly reconfigure visual representations in ventral temporal cortex via medial frontal cortex modulation.

The paper identifies order-selective cells in the human brain that represent temporal order during memory encoding and retrieval, predicting memory accuracy.

Disrupting selective persistent activity with electrical stimulation impairs human working memory

This study shows that disrupting selective persistent neural activity in the hippocampus and ventral temporal cortex with electrical stimulation impairs human working memory performance.

Persistent activity during working memory maintenance predicts long-term memory formation in the human hippocampus

This study shows that persistent hippocampal activity during working memory maintenance predicts long-term memory formation in humans.

Neural dynamics underlying minute-timescale persistent behavior in the human brain

This study investigates how the human medial frontal cortex and hippocampus encode task context over time, revealing distinct coding strategies for maintaining and switching task sets.

Control of working memory maintenance by theta-gamma phase amplitude coupling of human hippocampal neurons

This study investigates how theta-gamma phase amplitude coupling in the hippocampus supports working memory by integrating cognitive control and improving memory fidelity.

The paper shows that human hippocampal neurons form abstract, disentangled representations during inferential reasoning tasks, which correlate with inference behavior.

Hippocampal Theta Phase Precession Supports Memory Formation and Retrieval of Naturalistic Experience in Humans

This study shows that phase precession in human hippocampal theta oscillations correlates with memory encoding and retrieval success during naturalistic experiences.

Neurons in human pre-supplementary motor area encode key computations for value-based choice

The paper investigates how neurons in the human pre-supplementary motor area (preSMA) encode decision variables during value-based choices, finding that preSMA neurons represent both separate pre-decision variables and an integrated utility signal.

Encoding of predictive associations in human prefrontal and medial temporal neurons during Pavlovian conditioning

This study examines how human neurons in prefrontal and medial temporal regions encode predictive associations during Pavlovian conditioning, revealing distinct roles in value prediction and error signaling.

The geometry of domain-general performance monitoring in the human medial frontal cortex

This study investigates how neurons in the human medial frontal cortex represent cognitive conflict across tasks, showing both task-specific and generalized representations.

Cognitive boundary signals in the human medial temporal lobe shape episodic memory representation

This study identifies neurons in the human medial temporal lobe that signal cognitive boundaries between episodic events and shows these signals correlate with memory accuracy and temporal order recall.

Distinct roles of dorsal and ventral subthalamic neurons in action selection and cancellation

This study identifies distinct roles of dorsal and ventral subthalamic neurons in action selection and cancellation during a stop-signal task in humans.

Flexible recruitment of memory-based choice representations by human medial-frontal cortex

The paper shows that the medial frontal cortex flexibly uses memory-based representations during decision-making, while the medial temporal lobe does not show similar task-dependent changes.

Value-related neuronal responses in the human amygdala during observational learning
