A 39-year-old right-handed woman suffered a ruptured pericallosal aneurysm. Serial MRI studies showed damage to the genu and most of the body of the corpus callosum but not the splenium. Both supplementary motor areas (SMA) appeared intact. We studied the patient's praxis performance at intervals over a 4-month period with a standardized battery.

Pattern of callose deposition during the course of meiotic diplospory in Chondrilla juncea (Asteraceae, Cichorioideae) [PDF]
Protoplasma, 2016 Total absence of callose in the ovules of diplosporous species has been previously suggested. This paper is the first description of callose events in the ovules of Chondrilla juncea, which exhibits meiotic diplospory of the Taraxacum type.

Callose implication in stomatal opening and closure in the fern Asplenium nidus
New Phytologist, 2010 •The involvement of callose in the mechanism of stomatal pore opening and closing in the fern Asplenium nidus was investigated by examination of the pattern of callose deposition in open and closed stomata, and by examination of the effects of callose ...

Location of cellulose and callose in pollen tubes and grains of Nicotiana tabacum
Planta, 1998 The distribution of cellulose and callose in the walls of pollen tubes and grains of Nicotiana tabacum L. was examined by electron microscopy using gold-labelled cellobiohydrolase for cellulose and a (1,3)-β-D-glucan-specific monoclonal antibody for ...

Callosal Neglect in Hydrocephalus
Neurocase, 2006A functional disconnection of the corpus callosum (CC) can induce a form of spatial neglect where each hand (e.g., left) when attempting to bisect lines in the opposite (e.g., right) hemispace deviates toward its own (e.g., left) hemispace. Patients with hydrocephalus often show thinning of the CC but callosal neglect has not been reported in this ...

Abstract Over the past century numerous cytochemical studies have shown that after various types of stress the polysaccharide callose is deposited, at selected sites, on to the plant cell wall. Callose mainly consists of linear 13-1, 3-glucanase (1-4), and one of its functions is to close the connections that unite protoplasts of ...

Previous theories concerning the function of the corpus callosum have included a "topographic" column-to-column excitatory theory and a diffuse "regional" inhibitory theory. Here it is shown that a topographic inhibitory model, in conjunction with a postulate concerning surround inhibition among cortical columns, produces complementary patterns of ...

The corpus callosum is the main white matter tract between the two cerebral hemispheres and it connects both homolog and heterotopic regions in both hemispheres. The approximately 200 million axons are neatly organized from front to back with respect to which areas are connected.

Abstract The collections of nerve fibers that directly connect one cerebral hemisphere with the other, called the “cerebral commissures,” include the corpus callosum, the anterior commissure, and the hippocampal commissures. Of these, the corpus callosum (CC) is by far the largest, with at least 200 million fibers. The 2 X 10 estimate of
