Monkey electrophysiology suggests that the activity of the ventral tegmental area (VTA) helps regulate reinforcement learning and motivated behavior, in part by broadcasting prediction error signals throughout the reward system. However, electrophysiological studies do not allow causal inferences regarding the activity of VTA neurons with respect to these(More)
This study was designed to assess the use of ultrasonography in evaluation of trauma patients to see any intraperitoneal collection, collection in pleural cavity, any vital organ injury or any localized collection in blunt trauma to abdomen.

Reward seeking shapes our interactions with the environment, but whether it also influences how we perceive it remains controversial. Notably, there is currently a debate on whether objects that are more likely to provide high reward might be perceived bigger than those associated with low reward. The aim of this study is to test this « wishful seeing »(More)
The cortical network that processes visual cues to self-motion was characterized with functional magnetic resonance imaging in 3 awake behaving macaques. The experimental protocol was similar to previous human studies in which the responses to a single large optic flow patch were contrasted with responses to an array of 9 similar flow patches. This(More)
This cross sectional study was carried out in the Department of Radiology and Imaging, Bangabandhu Sheikh Mujib Medical University, Bangladesh in collaboration with the Department of Endocrinology and Department of Histopathology of the same hospital during the period of March 2007 to February 2008 to determine efficacy of ultrasonogram in the evaluation of(More)
Hepatobiliary ascariasis is common in developing countries where there is a low standard of public health and hygiene. We are reporting a rare case of ascariasis which induced multiple liver abscesses in a post menopausal woman who presented with fever, anorexia, nausea, vomiting and mild hepatomegaly. Ultrasonography revealed biliary ascariasis with(More)
The purpose of this study was to determine the usefulness of color doppler sonography and resistivity index (RI) in differentiating liver tumors. The study was carried out in the Department of Radiology and Imaging, Mymensingh Medical College Hospital, and Institute of Nuclear Medicine and Allied Sciences (INMAS), Mymensingh, Bangladesh, during the period(More)
Twin pregnancy is common but conjoined twins are an extremely rare congenital malformation without any known genetic predisposition. The incidence of conjoined twins is estimated to be around 1 in 250,000 live births with a female predilection. We presented an extremely rare case of abdomino-thoracopagus with single heart and liver. In this paper, the(More)
