DOI: 10.1002/hbm.70177
Abstract: Negative BOLD fMRI responses (NBR) occur commonly in sensory cortex and default mode network regions but remain poorly utilized as a marker of brain function due to an incomplete understanding. To better understand how NBR… read more here.

DOI: 10.1038/s41467-020-15928-z
Abstract: Goal-directed behavior requires the representation of a task-set that defines the task-relevance of stimuli and guides stimulus-action mappings. Past experience provides one source of knowledge about likely task demands in the present, with learning enabling… read more here.

DOI: 10.1097/aud.0000000000001508
Abstract: Objectives: Listening effort involves the mental effort required to perceive an auditory stimulus, for example in noisy environments. Prolonged increased listening effort, for example due to impaired hearing ability, may increase risk of health complications.… read more here.

DOI: 10.3389/fnins.2021.775256
Abstract: Top-down attention is a dynamic cognitive process that facilitates the detection of the task-relevant stimuli from our complex sensory environment. A neural mechanism capable of deployment under specific task-demand conditions would be crucial to efficiently… read more here.
