“…One seizure began with paroxysms of crying, which involved bilateral ''eye blinking'' movements and paroxysmal respiratory movement. These semiological features are most consistent with predominant activation of M3, which, in classical studies in monkeys, showed respiratory changes and facial movements, [12][13][14][15] and, in more recent studies, bilateral projections for activation of the upper facial musculature. 8 The semiology of right hemifacial tonic motor movements is most consistent with predominant activation of M4, which shows projections to contralateral lower facial musculature.…”

“…For instance, one feature that appears fairly specific to the cingulate cortex is calretinin-immunoreactive pyramidal neurons in layer V. These are found almost exclusively in the anterior portions of the cingulate gyrus, and are most numerous in areas 25 and 24. The region thus delineated corresponds closely to the areas whose stimulation gives rise to autonomic effects and vocalization in both macaque monkey and human (Smith, 1945;Pool and Ransohoff, 1949;Kaada, 1951;Pool, 1954;Showers and Crosby, 1958;Dua and MacLean, 1964;Robinson and Mishkin, 1968;Jü rgens and Ploog, 1970;Jü rgens, 1983). Studies that have analyzed other systems, such as response selection, spatial memory and selective attention have used functional imaging techniques, whose resolution limited the precise localization of function (Petersen et al, 1988;Pardo et al, 1990;Corbetta et al, 1991;Deiber et al, 1991;Bench et al, 1993;Hsieh et al, 1994;Lang et al, 1994;Larrue et al, 1994;Raichle et al, 1994).…”

Neurofilament and calcium-binding proteins in the human cingulate cortex

Functional imaging studies of the human brain have suggested the involvement of the cingulate gyrus in a wide variety of affective, cognitive, motor, and sensory functions. These studies highlighted the need for detailed anatomic analyses to delineate its many cortical fields more clearly. In the present study, neurofilament protein, and the calcium-binding proteins parvalbumin, calbindin, and calretinin were used as neurochemical markers to study the differences among areas and subareas in the distributions of particular cell types or neuropil staining patterns. The most rostral parts of the anterior cingulate cortex were marked by a lower density of neurofilament protein-containing neurons, which were virtually restricted to layers V and VI. Immunoreactive layer III neurons, in contrast, were sparse in the anterior cingulate cortex, and reached maximal densities in the posterior cingulate cortex. These neurons were more prevalent in dorsal than in ventral portions of the gyrus. Parvalbumin-immunoreactive neurons generally had the same distribution. Calbindin- and calretinin-immunoreactive nonpyramidal neurons had a more uniform distribution along the gyrus. Calbindin-immunoreactive pyramidal neurons were more abundant anteriorly than posteriorly, and a population of calretinin-immunoreactive pyramidal-like neurons in layer V was found largely in the most anterior and ventral portions of the gyrus. Neuropil labeling with parvalbumin and calbindin was most dense in layer III of the anterior cingulate cortex. In addition, parvalbumin-immunoreactive axonal cartridges were most dense in layer V of area 24a. Calretinin immunoreactivity showed less regional specificity, with the exception of areas 29 and 30. These chemoarchitectonic features may represent cellular reflections of functional specializations in distinct domains of the cingulate cortex.

“…Tachycardia was the principal response often independent of blood pressure changes although contemporaneous investigations did not note this precise independence (45,75). Areas from which changes in heart rate have been elicited in these early studies include: the frontal lobes (71,140,347), subcallosal gyrus (138), septal area (293), temporal pole, and cingulate gyrus (199,321) without a specific study of lateralization. In humans, Pool and Ransohof showed that heart rate changes were elicitable from the anterior cingulate cortex (ACC) and the posterior orbital cortex (253).…”

Cortical representation of the heart challenges the orthodox view that cardiac regulation is confined to stereotyped, preprogrammed and rigid responses to exteroceptive or interoceptive environmental stimuli. The insula has been the region most studied in this regard; the results of clinical, experimental, and functional radiological studies show a complex interweave of activity with patterns dynamically varying regarding lateralization and antero-posterior distribution of responsive insular regions. Either acting alone or together with other cortical areas including the anterior cingulate, medial prefrontal, and orbito-frontal cortices as part of a concerted network, the insula can imbue perceptions with autonomic color providing emotional salience, and aiding in learning and behavioral decision choice. In these functions, cardiovascular input and the right anterior insula appear to play an important, if not pivotal role. At a more basic level, the insula gauges cardiovascular responses to exteroceptive and interoceptive stimuli, taking into account memory, cognitive, and reflexive constructs thereby ensuring appropriate survival responses and maintaining emotional and physiological homeostasis. When acquired derangements to the insula occur after stroke, during a seizure or from abnormal central processing of interoceptive or exteroceptive environmental cues as in psychiatric disorders, serious consequences can arise including cardiac electrophysiological, structural and contractile dysfunction and sudden cardiac death.
