Distinctive responses in anterior temporal lobe and ventrolateral prefrontal cortex during categorization of semantic information

Scientific Reports, 2021
Semantic categorization is a fundamental ability in language as well as in interaction with the environment. However, it is unclear what cognitive and neural basis generates this flexible and context dependent categorization of semantic information.

Impact of depressed state on attention and language processing during news broadcasts: EEG analysis and machine learning approach

Scientific Reports, 2022
While information enriches daily life, it can also sometimes have a negative impact, depending on an individual’s mental state. We recorded electroencephalogram (EEG) signals from depressed and non-depressed individuals classified based on the Beck ...

The pedunculopontine tegmental nucleus as a motor and cognitive interface between the cerebellum and basal ganglia

Frontiers in Neuroanatomy, 2016
As an important component of ascending activating systems, brainstem cholinergic neurons in the pedunculopontine tegmental nucleus (PPTg) are involved in the regulation of motor control (locomotion, posture and gaze) and cognitive processes (attention ...

Reward and behavioral factors contributing to the tonic activity of monkey pedunculopontine tegmental nucleus neurons during saccade tasks

Frontiers in Systems Neuroscience, 2016
The pedunculopontine tegmental nucleus (PPTg) in the brainstem plays a role in controlling reinforcement learning and executing conditioned behavior. We previously examined activity of PPTg neurons in monkeys during a reward-conditioned, visually guided ...
