In this study the cross-sectional area (in n = 14 female controls, 15 male controls, 11 female patients with schizophrenia, 15 male patients with schizophrenia) and fibre composition (in n = 11 female controls, 10 male controls, 10 female patients with schizophrenia, 10 male patients with schizophrenia) of the corpus callosum in post-mortem control and schizophrenic brains was examined. A gende...

”Thinohyus” osmonti was based on a nearly complete skull and jaws (UCMP 393) found in the upper John Day beds (upper Oligocene) of Oregon, and named by W.J. Sinclair in 1905. Since its discovery, it has been transferred from one primitive peccary genus to another (Thinohyus, Bothrolabis, Perchoerus), without a careful examination of the excellent fossils. It is not referable to Thinohyus from t...

Abstract Recent phylogenetic studies amended the taxonomy of three-toed jerboas (subfamily Dipodinae), including raising subspecies to full species. Here, we use geometric morphometrics compare scaled-shape differences in dipodine crania while considering their revised taxonomy. We sampled Dipus deasyi, D. sagitta halli, s. sowerbyi, Jaculus blanfordi blanfordi, J. hirtipes, jaculus, loftusi, o...

Orientogeochus rheinheimeri gen. et sp. n. is described and illustra¬ted from Luzon (the Philippines). The new genus differs the Afrogeochus in toothed femora, rounded eyes, widely separated procoxal cavities, subapically inserted antennae rostrum almost three times as long base, widened at apex. A key to genera of subtribe Geochina distribution map for species are given.

CURRENT SCIENCE, VOL. 88, NO. 12, 25 JUNE 2005 1897 It provides an important link in the evolution of insects. The morphological characters of the reported bug, such as small body, short antennae comprising three segments, three-segmented, backwardly directed rostrum with thorax being the largest among the three parts of the insect body, are not yet known in a living or fossil insect family. It...

A new interstitial copepod of the family Laophontidae was found in the samples from a sandy beach at Taean, west coast of Korea. This species was described and named as Quinquelaophonte koreana sp. nov. Present new species is clearly distinguishable from its congeners with the combined characters of the short caudal ramus and its short ornamented seta V, two setae on the antennary exopod, and s...

The septal area is an important anterior component of the limbic system. It is located on the medial surface of the cerebral hemisphere nestled inferior to the rostrum of the corpus callosum and anterior to the third ventricle and lamina terminalis (Fig 1) (1). This small area is contiguous with components of the limbic system curving around the corpus callosum (Fig 2) as well as structures on ...

Bottlenose dolphin (Tursiops truncatus) echolocation resolution greatly exceeds measured beampattern and conventional hearing model performance. We explore the idea that teeth might aid conventional hearing. Nerve conduction requires neural delay lines, a requisite that might be met by unexplained specialised cell arrangements already reported. Jawbone resonance displays selectivity at 25-35 de...

Gender differences in brain structure and function have long been an interest to neuroscientists. One region where these differences have been reported is in the band of white matter that connects the two cerebral hemisphere, the corpus callosum. The current study explores the possibility that differences in cognitive ability contribute to the observed gender effects. The focus here is on visuo...
