TLDR
Responses recorded from 489 single neurons in the amygdalae of 41 neurosurgical patients were analyzed and a categorical selectivity for pictures of animals in the right amygdala was found.Abstract:
The amygdala is important in emotion, but it remains unknown whether it is specialized for certain stimulus categories. We analyzed responses recorded from 489 single neurons in the amygdalae of 41 neurosurgical patients and found a categorical selectivity for pictures of animals in the right amygdala. This selectivity appeared to be independent of emotional valence or arousal and may reflect the importance that animals held throughout our evolutionary past.read more

TL;DR: Representational geometry is a framework that enables us to relate brain, computation, and cognition and review recent insights into perception, cognition, memory, and action.

TL;DR: Overall, iEEG research on HFA should play an increasing role in cognitive neuroscience in humans, because it can be explicitly linked to basic research in animals, and the future evolution of this field is discussed.

Unconscious processing of emotions and the right hemisphere.
TL;DR: If the right hemisphere may also play a critical role in dynamic unconscious phenomena, such as anosognosia/denial of hemiplegia in patients with unilateral brain lesions is evaluated.

Persistently active neurons in human medial frontal and medial temporal lobe support working memory.
TL;DR: Direct evidence is revealed for a distributed network of persistently active neurons supporting working memory maintenance in the human medial frontal cortex and medial temporal lobe while subjects held up to three items in memory.

Statistical Aspects of the Analysis of Data From Retrospective Studies of Disease
Nathan Mantel,William Haenszel +1 more
TL;DR: In this paper, the role and limitations of retrospective investigations of factors possibly associated with the occurrence of a disease are discussed and their relationship to forward-type studies emphasized, and examples of situations in which misleading associations could arise through the use of inappropriate control groups are presented.

The Fusiform Face Area: A Module in Human Extrastriate Cortex Specialized for Face Perception
TL;DR: The data allow us to reject alternative accounts of the function of the fusiform face area (area “FF”) that appeal to visual attention, subordinate-level classification, or general processing of any animate or human forms, demonstrating that this region is selectively involved in the perception of faces.

Hierarchical clustering schemes
TL;DR: A useful correspondence is developed between any hierarchical system of such clusters, and a particular type of distance measure, that gives rise to two methods of clustering that are computationally rapid and invariant under monotonic transformations of the data.

Speed of processing in the human visual system.
TL;DR: The visual processing needed to perform this highly demanding task can be achieved in under 150 ms, and ERP analysis revealed a frontal negativity specific to no-go trials that develops roughly 150 ms after stimulus onset.
Journal ArticleDOI
Electrophysiological studies of face perception in humans
TL;DR: The differential sensitivity of N170 to eyes in isolation suggests that N170 may reflect the activation of an eye-sensitive region of cortex, and the voltage distribution of N 170 over the scalp is consistent with a neural generator located in the occipitotemporal sulcus lateral to the fusiform/inferior temporal region that generates N200.
