The residual effects of benzodiazepines on attention and psychomotor performance have been extensively documented.

My research areas include behavioral pharmacology, substance abuse, and behavioral neuroscience. The general focus of my program concerns how acute doses of abused drugs alter behavioral and cognitive functioning in humans. The research combines measures of drug effects on cognitive processes with conventional assessments of abuse potential, based on subjective rewarding effects of the drug, and its ability to reinforce self-administration. The objective of these studies is to improve our understanding of how basic cognitive and behavioral mechanisms play a role in the development of substance abuse and drug addiction. Several cognitive and behavioral functions are evaluated, including: behavioral inhibition, memory, motor coordination, and information processing, and simulated driving performance.

Effects of etizolam and ethyl loflazepate on the P300 event-related potential in healthy subjects

Figure 1. Emotion face assessment task. Blocks of each target emotion consisted of six 5-second angry, fearful, or happy face trials; blocks of ovals or circles consisted of two 5-second trials. Figure 2. Behavioral effects of placebo and 0. Lorazepam had no effect on response latency A , the fraction of correct responses, or accuracy B. Error bars indicate SE.

The functional anatomy of attention: a DCM study

Attention, predictions and expectations, and their violation: attentional control in the human brain View all 19 Articles. Recent formulations of attention—in terms of predictive coding—associate attentional gain with the expected precision of sensory information. Formal models of the Posner paradigm suggest that validity effects can be explained in a principled Bayes optimal fashion in terms of a cue-dependent setting of precision or gain on the sensory channels reporting anticipated target locations, which is updated selectively by invalid targets. This normative model is equipped with a biologically plausible process theory in the form of predictive coding, where precision is encoded by the gain of superficial pyramidal cells reporting prediction error. We used dynamic causal modeling to assess the evidence in magnetoencephalographic responses for cue-dependent and top-down updating of superficial pyramidal cell gain.

Dr Mohan Z Mani "Thank you very much for having published my article in record time. I would like to compliment you and your entire staff for your promptness, courtesy, and willingness to be customer friendly, which is quite unusual. I was given your reference by a colleague in pathology,and was able to directly phone your editorial office for clarifications. I would particularly like to thank the publication managers and the Assistant Editor who were following up my article. I would also like to thank you for adjusting the money I paid initially into payment for my modified article,and refunding the balance. Somashekhar Nimbalkar "Over the last few years, we have published our research regularly in Journal of Clinical and Diagnostic Research.

Analysis of the influence of bromazepam on cognitive performance through the visual evoked potential P Benzodiazepines have been used in the pharmacological treatment of anxiety for over four decades. However, very few studies have combined bromazepam and event-related potentials ERP. The present study aimed at investigating the modulatory effects of this drug on brain dynamics. Specifically, the effects of bromazepam 3mg on the P component of the ERP were tested in a double-blind experiment. The sample, consisting of 15 healthy subjects 7 male and 8 female , was submitted to a visual discrimination task, which employed the "oddball" paradigm. Electrophysiological P and behavioral measures stroop, digit span, and reaction time were analyzed across three experimental conditions: placebo 1, placebo 2, and bromazepam.

Effects of Triazolam on Brain Activity During Episodic Memory Encoding: A PET Study

Metrics details. Benzodiazepines carry the risk of inducing cognitive impairments, which may go unnoticed while profoundly disturbing social activity. Furthermore, these impairments are partly associated with the elimination half-life EH of the substance from the body. The object of the present study was to examine the effects of etizolam and ethyl loflazepate, with EHs of 6 h and h, respectively, on information processing in healthy subjects.
