Utilisation Behaviour (UB) denotes the appropriate usage of an object by a patient, however at an inappropriate situation. Patients are compelled by the visual, visual-tactile presentation to grasp and use the object kept in front of them. UB is observed in patients having unilateral or bilateral frontal lesions. It is considered to be an extension of magnetic apraxia, which is defined as bilateral manual grasping behavior. The proposed hypothesis is that in frontal lesions there is suppression of the inhibitory effect of frontal lobe on parietal lobe. Neurological models to explain this phenomenon to occur as a result of loss of inhibitory biological system within the brain. A disturbance of balance between the patient's dependence on and independence from the outside world is believed to be present in such cases. From a cognitive point of view, three models have been described. Since its first description by Lhermitte in 1983, UB remains to be an interesting neurological phenomenon. We present a case of UB in a patient of fronto-temporal dementia and also summarise the neurological and cognitive models that explain this behaviour.

“…In terms of mechanism, although both phenomenon are associated with loss of the capacity to inhibit stimulus-driven actions, however, patients of utilization behavior also lose the capacity to generate and act on endogenous intentions which is retained in alien limb phenomenon. [ 7 8 ]…”

Journal of Psychiatry AbstractAsymmetries of visuospatial attention has long been described in hemispatial neglect, a neurological syndrome in which brain damaged patients fail to acknowledge or explore stimuli presented to the contralesional side of space. Asymmetries for spatial attention were also investigated in schizophrenia. In this review, we report the researches that, using tasks selectively employed to study visuospatial processing in neglect patients, demonstrated hemineglect-like behaviour in schizophrenia. Intriguingly, these studies produced mixed evidence. Some researches found biases towards the left hemispace suggesting a right hemineglect, others towards the right hemispace suggesting a left hemineglect. We examine the possible factors that may have contributed in producing these conflicting findings.

“…1 However, case reports document various locations responsible for this behavior ranging from lesions of orbitofrontal lobes to fronto-striatal projections. 3 Mesulam 4 divided the frontal lobe into the following 3 components: the "motor-premotor component," the "paralimbic cortex," and the "heteromodal association cortex." Goldberg 5 hypothesized that utilization behavior arises as a result of "medial system" (including the supplementary motor area [SMA] and cingulate gyrus) lesions causing a loss of internally driven actions and overdominance of externally driven actions controlled by "lateral systems.…”
