12 Physiological psychology What does the brain do? Generalization and reduction Generalization-a type of scientific explanations; a general conclusion based on many observations of similar phenomena. Reduction, a type of scientific explanation; a phenomenon is described in terms of the more elementory processes that underlie it.
13 Biological root Descartes Reflexes Dualism, but believe that the connection between mind and body is mechanical. The pineal body.
14 Reflexes
15 Biological root Johannes Muller Doctrine of specific nerve energies Because all nerve fibers carry the same type of message, sensory information must be specified by the particular nerve fibers that are active Pierre Flourens Experimental ablation, like modal gene knock out The research method in which the function of a part of the brain is inferred by observing the behaviors an animal can no longer perform after that part is damaged. Broca s area
16 Natural selection and evolution Darwin: natural selection and evolution All of an organism s characteristics-its structure, its coloration, its behavior- have functional significance. Functionalism The principle that the best way to understand a biological phenomenon (a behavior or a physiological structure) is to try to understand its useful functions for the organisms. Natural selection Mutation Selective advantage
17 Schematic representation of how antibiotic resistance is enhanced by natural selection. The top section represents a population of bacteria before exposure to an antibiotic. The middle section shows the population directly after exposure, the phase in which selection took place. The last section shows the distribution of resistance in a new generation of bacteria. The legend indicates the resistance levels of individuals.
18 Natural selection is the biological theory that explains why living creatures seem to match their environmental niches so well the process by which individual organisms with favorable traits are more likely to survive and reproduce than those with unfavorable traits. Insofar as there is genetic variability for the trait under selection, the genotypes associated with the favored traits will increase in frequency in the next generation. Natural selection is simply the logical result of four features of living systems: variation - individuals in a population vary from one another inheritance - parents pass on their traits to their offspring genetically selection - some variants reproduce more than others time - successful variations accumulate over many generations
19 Natural Selection Requires... For natural selection to occur, two requirements are essential: There must be heritable variation for some trait. Examples: beak size, color pattern, thickness of skin, fleetness. There must be differential survival and reproduction associated with the possession of that trait. Unless both these requirements are met, adaptation by natural selection cannot occur. Some examples: If some plants grow taller than others and so are better able to avoid shading by others, they will produce more offspring. The reason they grow tall is because of the soil in which their seeds happened to land, and not because they have the genes to grow tall, Will evolution occur? If some individuals are fleeter than others because of differences in their genes, but the predator is so much faster that it does not matter, will evolution occur?
20 Evolution Evolution Vertebrate evolution 360mya: Amphibian therapsids catastrophic series of volcanic eruptions Cynodont ancestor of mammals small, nocturnal, eat insects and live in trees 65mya: dinosaurs extinction, primates
21 Evolution of human beings 25mya: Hominids orangutans, gorillas, chimpanzees, humans 3.7mya: bipedalism, 2.5mya:tools 1.7mya: Homo erectus, Africa to Europe and Asia; Homo neanderthalis, Homo sapiens
22 Evolution of large brains Human vs. chimpanzee: 1.2% difference in DNA; size 3 times larger
23 Neoteny: A slowing of the process of maturation, allowing more time for growth; an important factor in the development of large brains
24 Ethical issues in research with animals Research using animals are beneficial to human beings and to other animals. We should treat animals humanely. Animal models are very important in research, examples.
