Visually guided behavior requires transforming sensory inputs into decisions based on behavioral goals. Inferotemporal cortex (IT) is traditionally seen as a perceptual stage that provides object representations for downstream decision circuits. Here, we show that neurons in anterior IT (area TEa) reflect core elements…

Primate brains typically have regions within the ventral visual stream that are selectively responsive to faces. These face patches are located in similar parts of macaque inferotemporal (IT) cortex across individuals though correspondence with particular anatomical features has not been previously reported. Here…

Disconnection of the frontal lobe from the inferotemporal cortex produces deficits in a number of cognitive tasks that require the application of memory-dependent rules to visual stimuli. The specific regions of frontal cortex that interact with the temporal lobe in performance of these tasks remain undefined. One…

Both frontal-inferotemporal disconnection and fornix transection (Fx) in the monkey impair object-in-place scene learning, a model of human episodic memory. If the contribution of the fornix to scene learning is via interaction with or modulation of frontal-temporal interaction − that is, if they form a unitary system…

It is well known that expectations influence how we perceive the world. Yet the neural mechanisms underlying this process remain unclear. Studies have focused so far on artificial contingencies between simple neutral cues and events. Real-world expectations are however often generated from complex associations between…

Saccadic eye movements are an inherent component of natural reading, yet their contribution to information processing at subsequent fixation remains elusive. Here we use anatomically-constrained magnetoencephalography (MEG) to examine cortical activity following saccades as healthy human subjects engaged in a one-back…

The inferior-fronto-occipital fasciculus (IFOF) is a long-range white matter tract that connects the prefrontal cortex with parietal, posterior temporal and occipital cortices. First identified in the 19th century through the pioneering studies of Mayo and Meynert using blunt dissection, its anatomy and function remain…

In this paper, we will provide an introduction to the brain structure and function. Brain is an astonishing living organ inside our heads, weighing about 1.5kg, consisting of billions of tiny cells. The brain enables us to sense the world around us (to touch, to smell, to see and to hear, etc.), to think and to respond…

Characterization of inter-regional interactions in brain is essential for understanding the mechanism relevant to normal brain function and neurological disease. The recently developed flexible micro (μ)-electrocorticography (μECoG) device is one prominent method used to examine large-scale cortical activity across…

The insular cortex is usually hidden underneath the inner surface of the operculum (). Once the dissection of the cortex and U fibers of the frontal, temporal, parietal, and occipital lobes is completed, it is possible to expose the insular cortex by lifting the operculum (; ). To enhance visualization of the white…

Functional magnetic resonance imaging (fMRI) has begun to narrow down the neural correlates of self-generated forms of thought, with current evidence pointing toward central roles for the default, frontoparietal, and visual networks. Recent work has linked the actual arising and generation of thoughts more specifically…

Non-sensory thalamic nuclei interact with the cortex through thalamocortical and cortico-basal gangliathalamocortical loops. Reciprocal connections between the mediodorsal thalamus (MD) and the prefrontal cortex are particularly important in cognition, while the reciprocal connections of the ventromedial (VM), ventral…

'Nicola Palomero-Gallagher'] Neurotransmitters and their receptors are key molecules in information transfer between neurons, thus enabling inter-areal communication. Therefore, multimodal atlases integrating the brain’s cyto- and receptor architecture constitute crucial tools to understand the relationship between its…
