The biological explanations of aggression say that aggression is caused by differences in the biological make-up of individuals one example of these biological differences that could cause aggression is neural mechanisms neurotransmitters neurotransmitters are chemicals which trigger a response in. Serotonin is most commonly believed to be a neurotransmitter, although some consider it to be a hormone it is produced in the intestines and the brain it is also present in the blood platelets and the central nervous system (cns) as it occurs widely throughout the body, it is believed to influence a variety of. The hypothalamus is the link between the endocrine and nervous systems the hypothalamus produces releasing and inhibiting hormones, which stop and start the production of other hormones throughout the body the hypothalamus plays a significant role in the endocrine system it is responsible for. Many studies have investigated the various neural and hormonal factors that influence the renal circulation as a result, we now have a relatively good understanding of how these regulatory mechanisms operate in isolation from each other (navar et al 1996 dibona & kopp, 1997) however, since the sympathetic nervous. The process of physiological stress response starts from the moment the body realizes the presence of the stressor, followed by the sending of signals to the brain, and to the specific sympathetic and hormonal responses to eliminate, reduce or cope with the stress. Issues debates and approaches (ida) for neural mechanisms and hormones as an explanation for aggression studies are correlational most research linking neurotransmitter or hormone levels and aggression is correlational correlations do not show causal links, and therefore another factor may mediate both the level of.

Vicarious learning is able to explain the aggression shown by participants in banduras study in the absence of direct reinforcement in banduras study, it biological research in the area of genetics and neural and hormonal mechanisms suggests that individual characteristics determine aggressive behaviour this would. Outline and evaluate neural and/or hormonal mechanisms in aggression (8 and 16 marks) the hormone testosterone is believed to influence aggression due to its action on the brain areas involved in social behaviour means that a biological explanation is insufficient on its own to explain all the different aspects of. Investigates how the nervous system and hormones work determines how the brain functions determines how changes in structure and function of these systems may affect behavior 3 many biopsychologists have concentrated on abnormal behavior and have tried to explain it in physiological terms. The need to find fuel to generate energy is a profound drive within the biology of all living organisms: we all need food to survive so it's not surprising that our bodies have such a complex system to control food intake, driven by hormones hormone levels also change when we lose weight as much as we.

Neural and hormonal mechanisms involved in the control of eating behaviour, including the role of biological explanations for anorexia nervosa, including genetic and neural explanations our switch from mainly vegetarian to an omnivorous diet has been used by some to explain the growth of the human brain. Central nervous system facts what are the different parts of the cns (diagram) the brain and cerebrum the central structures of the brain the base of the brain the it also secretes hormones that stimulate or suppress the release of hormones (for example, growth hormones) in the pituitary gland. The endocrine system works together with the nervous system to influence many aspects of human behavior, including growth, reproduction, and metabolism and the endocrine system plays a vital role in emotions because the glands in men and women differ, hormones also help explain some of the observed behavioral. For example it fails to explain why we eat even though we are not hungry or in a state of satiety, the reason to this issue is likely to be in the behavioural explanation of eating behaviour eg the role of social learning and scheduled feeding a further criticism of the role of neural mechanisms, in the control of eating and.

Finally, in the last two sections (§§4 and 5), we discuss in which ways hormones may explain variation in cooperative behaviour within individuals, between in short, there is a continuum from neurocrine to endocrine communication, and hormonal and neural mechanisms are interconnected with multiple reciprocal effects. Learning objectives by the end of this section, you will be able to: discuss the role of neural regulation in digestive processes explain how hormones regulate digestion the brain is the control center for the sensation of hunger and satiety the functions of the digestive system are regulated through neural and hormonal. In response to acute stress, the body's sympathetic nervous system is activated due to the sudden release of hormones the sympathetic nervous systems stimulate the adrenal glands triggering the release of catecholamines, which include adrenaline and noradrenaline this results in an increase in heart.

Receptors in muscles provide the brain with information about body position and movement the brain controls the contraction of skeletal muscle the nervous system regulates the speed at which food moves through the digestive tract endocrine system the endocrine system secretes hormones into blood and other body. An alternative way of looking at the biological causes of offending behaviour is to examine neurochemical (neurotransmitters) and neurophysiological. The distinctions between neural and endocrine regulation, no longer as clear-cut as they once seemed to be, are further weakened by the fact that neurosecretory moreover, the molecular structures of prolactin and growth hormone are similar, which may explain why they show some overlap in biological properties.

Scripts: alternative answers not already covered by the mark scheme are discussed and legislated for 2 marks for clear and coherent outline which explains how explanations vary from those at a lower 1 mark – ghrelin is a hormone/chemical released from stomach and small intestine into the. Changes in connectivity between different nodes of the network can also explain behavioral plasticity and can be accomplished by changes in dendritic structure, such as density of dendritic spines and synapses, or by retraction or outgrowth of. Define the basic terminology and basic principles of hormone–behavior interactions explain the role of hormones in behavioral sex differentiation explain the role of hormones in aggressive behavior explain the role of hormones in parental behavior provide examples of some common hormone– behavior interactions.

From the blood stream, the hormones communicate with the body by heading towards their target cell to bring about a particular change or effect to that cell the hormone can also create changes in the cells of surrounding tissues ( paracrine effect) the endocrine system works with the nervous system and the immune. Possible to use endocrine tools to explain a mammalian behaviour, we analysed lordosis behaviour neuronal explanations of biologically regulated behaviours in experi- mental animals or in humans, neurobiologists have analyse the neural, hormonal and genomic steps involved in producing a mammalian behaviour. Neural and hormonal causes of aggression genetical origins of aggression ethological explanation of aggression evolutionary explanations of human and that these were slightly more aggressive and slightly less intelligent but this is such a rare mutation that it does not explain aggression in the general population.
