The ability of aquatic vertebrates to maintain their position requires integration of visual and vestibular sensory information. To understand better how aquatic animals integrate such information, we measured the optomotor behaviour of Xenopus laevis tadpoles raised in growth chambers in microgravity (< 10(-3)g), normal gravity (1 g), hypergravity (3 g) and on a slowly rotating clinostat (simu...

Twenty-eight children with attention-deficit hyperactivity disorder (ADHD) were examined with SPECT (single photon emission computed tomography). Seven of the children had abnormal distribution of the regional cerebral blood-flow (rCBF) on visual evaluation and 10 had abnormal EEG findings. The only clinical finding that differentiated the group with normal from abnormal rCBF was behaviour symp...

It is important to control abnormal behaviour and hyperactivity, and improve cognition in mentally retarded children (MRC), which would help in their education, training and subsequent rehabilitation. Recently it has become known that amongst other side-effects, protracted use of anti-convulsant medication induces cognitive and behavioural dysfunction, which is a major problem in mentally retar...

OBJECTIVE The aim of this study was to explore the eating behaviour in people with a specific phobia of vomiting (SPOV), and whether those identified as restricting their food had a greater degree of psychopathology and impairment than those who do not restrict their food. METHOD We recruited 94 participants with SPOV. They were divided into those who reported restricting their food (SPOV-R) ...

Despite extensive study on wireless sensor network security, defending internal attacks and finding abnormal behaviour of the sensor are still difficult and unsolved task. The conventional cryptographic technique does not give the robust security or detection process to save the network from internal attacker that cause by abnormal behavior. The insider attacker or abnormally behaved sensor ide...

Morality is among the most sophisticated features of human judgement, behaviour and, ultimately, mind. An individual who behaves immorally may violate ethical rules and civil rights, and may threaten others' individual liberty, sometimes becoming violent and aggressive. In recent years, neuroscience has shown a growing interest in human morality, and has advanced our understanding of the cognit...

Several reports have appeared on postanaesthetic convulsive disorders in humans after enflurane and isoflurane anaesthesia. However, it is controversial if enflurane induces epileptiform electroencephalogram (EEG), abnormal behaviour, or both, lasting for several days after anaesthesia in laboratory animals. We chronically implanted electrodes for EEG recording in the cortex, medial amygdala an...
