Sensation: Intro Sensation is the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment. Perception is the process of organizing and interpreting sensory information enabling us to recognize meaningful objects and events. Bottom-up processing is the analysis that begins with the sense receptors and works up to the brain’s integration of sensory information. Top-down processing is information processing guided by higher-level

The Diencephalon sits between the cerebral hemispheres and is superior to the midbrain‚ which is made up of the thalamus and hypothalamus structures. The functions of the diencephalon include: Sensing impulses directed throughout the Body‚ Controlling autonomic functions‚ controlling

in both experiments (Bennett 2000). The three sub factors of solar energy absorption include convection‚ conduction‚ and radiation. Convection is a continuous circulation of liquid or air that transfers thermal energy from hot to cold surfaces (Reece 2014). The process of heat gain is evident when blood transfers heat from the core of an organism’s body to the extremities (Reece 2014). Conduction transfers heat between substances that are in direct contact (Reece 2014). When a substance is heated‚

3.7. Dielectric Studies Dielectric properties are the complex function of bulk permittivity‚ conductivity‚ size‚ shape‚ frequency and spatial arrangement of the constituents [27]. The Dielectric complex permittivity is written as where‚ the real part εr and imaginary part ε″ are known as dielectric constant and dielectric loss accounts for the energy storage and energy loss respectively. The dielectric constant is calculated with the relation εr=Cd/εoA where‚ C is series capacitance

1. These cells generate a rhythmical depolarisation‚ which then spreads out over the atria to the atrio-ventricular node. 2. The atria then contract‚ pushing blood into the ventricles. 3. The electrical conduction passes via the Atrio-ventricular node to the bundle of His‚ which divides into right and left branches and then spreads out from the base of the ventricles across the myocardium. 4. This leads to a ’bottom-up’ contraction of the ventricles‚
