The hand is essential in humans for physical manipulation of their surrounding environment. Allowing the ability to grasp, and differentiated from other animals by an opposing thumb, the main functions include both fine and gross motor skills as well as being a key tool for sensing and understanding the immediate surroundings of their owner. Hand fractures are the most common fractures presenti...

Functional asymmetry of the parietal lobes during piano performance was assessed utilizing independent componentcross correlation-sequential epoch analysis of functional magnetic resonance imaging time series. Eight right handed musically trained subjects played the piano with their right hand, left hand, or both hands as cued by visually presented musical scores. The areas activated included t...

The aim of the study was to investigate fine motor performance and ascertain age-related changes in laterality between the dominant and non-dominant hand. A representative sample of 635 adults (144 males and 491 females) aged 50 years and over completed a test battery MLS (Motor Performance Series) to assess a broad range of hand functions. Functional asymmetry was observed in all four motor te...

This study examined hand preference in baboons in a sample of 94 subjects for a unimanual task and in a sample of 104 subjects for a bimanual task. For the unimanual task, handedness was assessed by observing simple reaching for grains. For the bimanual task, tubes lined with peanut butter inside were presented to the baboons. The hand and the finger used to remove peanut butter were recorded. ...

The primary visual area (V1) of the mammalian brain is a thin sheet of neurons. Because each neuron is dominated by either right or left eye one can treat V1 as a binary mixture of neurons. The spatial arrangement of neurons dominated by di erent eyes is known as the ocular dominance (OD) pattern. We propose a theory for OD patterns based on the premise that they are evolutionary adaptations to...

Objective: The ways people use for social rank (dominance vs prestige) could explain difference attitude toward five moral foundations. The aim of this study was to investigate the differential relationship between prestige, dominance and moral foundations.

There are profound sex differences in the incidence of many psychiatric disorders. While these disorders are frequently linked to social stress, little is known about sex differences in the underlying neural mechanisms. Individuals characterized by aggression and dominance are more resistant to social stress, whereas individuals characterized by docility and subordinace are more susceptible to ...

Palmaris longus is a thin fusiform shaped muscle which terminates as long slender tendon and enters the palmar aponeurosis of hand. It also one most variable muscles in body. The main objective this study was to detect its both hands compare analyse it relation gender hand dominance. An observational, descriptive conducted over period 11 months from October 2021 – August 2022 Department Human A...

to study inheritance of resistance to septoria tritici blotch in wheat, the generation mean analysis method was used. so six generations (p1, p2, f1, f2, bc1 and bc2) were planted under completely randomized design with three replications in greenhouse. seedlings were inoculated at the second-leaf stage with an isolate of septoria tritici and necrosis and picnidia density and area under disease...
