 APStracts 6:0078N, 1999.
In a recent functional magnetic resonance imaging study (fMRI), we reported the cortical areas activated in a thermal painful task and compared the extent of overlap between this cortical network and those activated during a vibrotactile task and a motor task (Gelnar et al.
Differentiating Cortical Areas Related to Pain Perception from Stimulus Identification: Temporal Analysis of fMRI Activations in a Painful Thermal Task.
Insular cortex at the level of the anterior commissure was the region best related to the thermal stimulus, and Brodmann's area 5/7 was the region best related to the pain perception.

Cortical areas were identified that were hypothesized to be involved in this effect, an electrical current source was hypothesized at that location, an electrical scalp distribution based on that cortical current source was generated, and the hypothesized and actual electrical distributions were compared.
“Brain electrical source analysis” (BESA, cortical source analysis) was used to identify the cortical areas involved in this ERP effect.
This area was activated most highly for validly cued targets relative to either control trials (no cue) or invalidly cued targets (contralateral cue).

The cortical source of this activity was the superior parietal lobe (Brodmann area 7).
They suggest that the affect of attention is to enhance the cortical areas involved in "stimulus orienting" and those involved in recognition memory.
Its cortical source was located in the posterior portion of the cingulate gyrus (Brodmann area 23).

For instance, the auditory cortex of a rat receives widespread projections from dopamine neurons in the ventral tegmental area, which are activated by new stimuli or unpredicted rewards, and reinforce cortical reorganization (Foote 1987).
Of greatest concern is whether there will be simultaneous increased cortical representation in three different areas of A1 upon presentation of the chord stimulus, or whether the lateral-inhibitory effects induced by the increased cortical representation in one of the three areas in question will interfere with the representation of another.
Platinum bipolar-stimulated electrodes are stereotaxically implanted within the right ventral tegmental area (4.5 mm posterior, 0.7 mm lateral and 8.5 mm ventral to Bregma) in female rats anesthetized with barbituate (300 g), using techniques approved under Stanford University's Animal Subject protocol.

 BASIC MOTOR PATHWAY
The precentral gyrus has many names: primary motor cortex, Brodmann's area 4, M1, etc. It provides the bulk of the corticospinal tract, but other cortical areas contribute as well.
Instead, the hands or face, which take up the most cortical area, are preferentially affected.
One such area is area 3a, part of primary somatosensory cortex, which is hidden down inside the central sulcus.

 How long before superintelligence?
There are genetically coded tendencies for certain brain areas to specialize on certain tasks (for example primary visual processing is usually performed in the primary visual cortex) but this does not mean that other cortical areas couldn't have learnt to perform the same function.
We calculate the average computer-equivalent processing capacity of a single neuron in that cortical area, and multiply this value with the number of neurons in the brain.
Other cortical areas take over the functions that would normally have been developed in the destroyed region.

Brodmann's areas,   areas of the cerebral cortex distinguished by hypothesized differences in the arrangement of their six cellular layers and identified by numbers; although the histologic basis is in dispute, the topographic numbering is widely used as a descriptor for mapping cortical locations that control different functions of the nervous system and the body.

 Defining Awareness by the Triangular Circuit Of Attention by David LaBerge
Since most of the knowledge we have of cortical and thalamic circuitry has been obtained from studies of the primary visual cortex and its adjacent areas, the description given here of the triangular circuit is based on a schematic diagram of the triangular circuit involving areas V1 and V2.
The results of the simulations in that study showed sharp increases in firing-rate trajectories in cortical cells corresponding to attended stimuli (relative to trajectories in cortical columns corresponding to neighboring unattended stimuli).
The forward connection from the first column (e.g., in area V1) to the second column (e.g., in area V2) occurs both directly and indirectly by means of a synapse in a thalamic nucleus, forming a triangular circuit.

 BioMed Central Full text An information integration theory of consciousness
Thus, the reason why certain cortical areas contribute to conscious experience of color and other parts to that of visual motion has to do with differences in the informational relationships both within each area and between each area and the rest of the main complex.
Thus, it is something having to do with the organization of certain cortical areas – and not with their inputs from the sensory periphery – that determines the quality of conscious experiences we can have.
Slow oscillations consist of a depolarized phase, during which the membrane potential of cortical neurons is close to firing threshold and spontaneous firing rates are similar to quiet wakefulness, and of a hyperpolarized phase, during which neurons become silent and are further away from firing threshold.

We analyzed the regional glucose metabolism of the corpus callosum and of speech-relevant cortical areas in 10 normal individuals at rest and during word repetition.
The study indicates that language processing in asymmetrically organized cortical areas inhibits the reciprocal transcallosal information exchange in favor of the lateralized mental operation.
The objective of this study was to measure functional activity of callosal fiber tracts during speech processing.
