ENERGY & PHARMACOLOGY Behavior and external / internal conditions Environment - External condition Process in the Body – Internal condition 52
ENERGY & PHARMACOLOGY Basic structure BEHAVIOR = Function { Internal stimulus, external stimulus} 53
ENERGY & PHARMACOLOGY Animal behavior and environment BEHAVIOR= Function {Process in the Body, nervous Body system structure, nervous function, hormonal effects , biological clocks, perceptual mechanisms, Genes, stimulus filtering} 54
ENERGY & PHARMACOLOGY External factor and environmental variables Temperature = function { temperature control Unit , CV } Airflow = function air-conditioning} Barometric pressure = function { place, time } Humidity = function { office level or place } Visual effect = function { walking researchers in the laboratory} Light = function { lights control unit} Sounds = function { sounds generating equipment, voices } Vibration = function { refrigerators, ventilators, PCs, specific equipment } Elektromagnetic waves = function{ transmitting equipment, magnets} Smell = function {specific gases, parfums, etc, } 55
ENERGY & PHARMACOLOGY Rule of energy preservation of the body E = K + P = constant n (Formula of energetic balance) Potential Energy of the Body P = ∆U+ δ(ε − Tη + Pν) -∆U -Ε is the change in biochemical energy is the internal energy - Tη - Pv is the entropy energy is thermodynamic energy 56
THE IMPORTANCE OF THE ENERGY PARAMETER IN BEHAVIORAL PHARMACOLOGY n Kinetical energy of body E k = Mv²/2 + δm ²R²/2 E (Locomotion) = Mv²/2 V = velocity, M = total mass of body E (Oscillation) = δm ω²R²/2 ω = radial frequency, R = radius of oscillation, δm = mass of oscillating body part 57
THE IMPORTANCE OF THE ENERGY PARAMETER IN BEHAVIORAL PHARMACOLOGY n Kinetical energy of body E (Locomotion) is the kinetic energy resulting from: Locomotion, Walking, Rearing, Climbing E (Oscillation) is the kinetic energy resulting from different repetitive movements: Scratching, Grooming , Chewing, Sniffing, Wet Dog Shakes, Head Twitches, Tremors 58
