13-14C (the Age of Discovery)
Columbus: discovering the New World = discovering American native (Indian) (people who made a voyage to the New World were present before the Columbus discovery)
→ persecution became violent to Indian afte the discovery
→ "Indian is not human", based on Biblicism

Ofune Site (大船遺跡)

Pit dwellings (竪穴住居)
Pit dwellings were common during the Jomon Period. A round or rectangular floor was dug into the ground, and posts were erected to create the framework for the dwellings. Soil or reeds were used to thatch the fremework and create a roof over the dwellings, which contained a fire pit built onto the floor.
The pit dwellings found on the Ofune Site are relatively large, including some that range in length from 8 -11 meters long and more than two meters deep. The fire pits appear to have gradually evolved over time, from being directly built onto the floor via to fire pits lined with pottery, and later to lined with stones. This restoration of a pit dwelling is based on information gathered from excavations, and employs wood from chestnut trees to reconstruct the framework used in pit dwellings.

Fig. 24.10. Kymograph records of the contractions of the flexor muscle of the propodite in the cheliped of a crayfish (Procambarus clarkii), showing mechanical inhibition of slow and fast contraction produced by repetitive stimulation of the appropriate inhibitory axon. A, isotonic mechanical record of contraction; B indicates stimulation of the slow (curve I) or fast (curve II) motor axon; C, time in second; D indicates stimulation of the inhibitory axon. Cruve I shows complete inhibition of the contraction; in curve II it can be seen that the same frequency of stimulation in the inhibitory axon results only in incomplete inhibition. Note that in the first curve of II stimulation of the inhibitory fiber commences before that of the motor axon. Notice the difference in speed of fthe slow and fast contractions, especially that of the uninhibited onset of the fast one (both contractions are elicited by the same freequency of stimulation).

Fig. 20.17. Inhibitory postssynaptic potentials recorded with an intracellular microelectrode from a stretch receptor neuron of a crayfish (Aseacus). Left, a diagram of part of the preparation; two receptor neurons innervated by branches of one common inhibitory axon. The inhibitory axon is stimulated through a pair of electrodes applied near the "lower"' nerve cell. The action potentials travel along the inhibitory axon and reach the inhibitory synapses on the other nerve cell, where The inhibitory postsynaptic potentials (i.p.s.p.'s) are are being recorded at the site indicated by the arrow. (Since the original publication of this figure it has been found that inhibitory synapses are also located close to the recording site.) Right, a series of records (numbered 1 through 8) showing three i.p.s.p.'s each (each is preceded by a small vertical deflection, the stimulus artifact). Before the inhibitory axon was stimulated, the membrane potential of the sensory cell was artificially depolarized or hyperpolarized to different degrees, except in the ease of record 4. Note that the i.p.s.p.'s are hyperpolarizing during depolarization, and increasingly depolarizing during hyperpolarization of the membrane. The resting membrane potential happens to be equal to the reversal potential of the i.p.s.p.'s. (Left: Kniller 1955, Right: Hagiwara et al. 1960).

Diagram of the main centers and "wiring" arrangement of a reptile, in which the tectal region of the midbrain plays a dominant role; the corpus striatum (basal ganglia) is of some importance as a correlation center, but the neocortex (neopallium) is unimportant. The reticular formation of the brain stem (cross hatched) is important in carrying motor impulses to nuclei of the stem and cord. In this oversimplified diagram only a limited number of paths between somatic receptors and effectors are included; visceral centers and paths are omitted, as are cerebellar connections.

In A (primitive stage) the hemisphere is merely an olfactory lobe. B (Amphibian), Dorsal and ventral areas, archipallium (hippocampus) and basal nuclei (corpus striatum) are differentiated. C (primitive reptile), The basal nuclei have moved to the inner part of the hemisphere. D (advanced reptile), The neopalliurn appears as a small area (in many reptiles). E (primitive mammal), The archipallium is forced to the median surface, but the neopalliuin is still of modest dimensions, and the olfactory areas are still prominent below the rhinal fissure (as in primitive mammals). F (advanced mammal), The primitive olfactory area is restricted to the ventral aspect, and the neopallial areas are greatly enlarged (as in advanced mammals). The various cellular compounds of the hemispheres are distinguished by color.

A, Primitive stage, essentially an olfactory lobe; gray matter internal and little differentiated. B, St e seen in modern amphibians. Gray matter still deep to surface, but differentiated into paleopalli (= olfactory lobe), archipallium (= hippocampus), and basal nuclei (= corpus striatum), the last be ming an association center, with connections from and to the thalamus (indicated by lines representing cut fiber bundles). C, More progressive stage, in which basal nuclei have moved to interior, and pallial areas are moving toward surface. D, Advanced reptilian stage; beginnings of neopallium. E, Primitive mammalian stage; neopallium expanded, with strong connections with brain stem; archipallium rolled medially as hippocampus; paleopallial area still prominent. F, Progressive mammal; neopallium greatly expanded and convoluted (包旋形・回旋状); paleopallium confined to restricted ventral ar a as pyriform lobe.

Fig. 3.15. Stereodiagram illustrating the principal neuronal types in the cerebellar cortex, the two afferent systems, and the interconnections between these elements. The mossy fiber afferents innervate granular cells and Golgi-cells in complex synaptic glomeruli. The granular cell axons then rise toward the surface of the cerebellum, where they branch to form parallel fibers that excite Purkinje cells, Golgi cells, basket cells, and stellate cells. The Purkinje cell axons constitute the only output from the cerebellar cortex. (Eccles et al. 1967)

A, Hypothetic primitive stage, in which brain stem centers were continuous with one another and with the columns of the cord. Even at such a stage, however, it would be assumed that special somatic centers would have developed for eye and ear. The brain region includes a special visceral motor column for the branchial muscles. B, Comparable diagram of the mammalian situation. The somatic sensory column is still essentially continuous (almost entirely associated with nerveV), but the other columns are broken into discrete nuclei. The visceral sensory column includes both a general visceral nucleus (mainly for afferent fibers from the viscera via the vagus) and a special nucleus for the important sense of taste. Of efferent visceral nuclei, there are small anterior ones for automonic eye reflexes and the salivary glands, and a large nucleus for parasympathetic fibers to the viscera via the vagus. There are important branchial motor nuclei for V, VI, and IX, X (ambiguus). The somatic motor column includes small nuclei for eye muscles anteriorly and a hypoglossal nucleus posteriorly.

Fig. 25.1. Fine structure of the insect ear as revealed by electron microscopy of the ear of the locust (Locusta migratoria). The eardrum, or tympanic membrane, is located laterally on the first abdominal segment. The auditory ganglion is attached to its inner surface. It contains 60 to 80 sensory neurons. Their perikaryon (p.c.) and axon (ax.) are surrounded by Schwann cells (S.c.); one Schwann cell enfolds several sensory neurons. The proximal part of the dendrite is enclosed by a fibrous sheath cell (f.c.); the distal part of the dendrite (den) is surrounded by another type of satellite cell, the scoloplle cell (sp.c.). A cilium (cil.) extends from the dendrite into a scolopale cap (cap.). This in turn is in rontaet with an attachment cell (a.c.) that connects with the hypoclermal cells (hyp.) of the elevated process of the tympanic membrane. The root (r.) and rootlets (r.l.) of the cilium can be seen inside the dendrites. Note the extracellular flied space (es) between the scolopale cells. The nature of the mechanical deformation of the sensory neurons during vibration of the tympanic membrane is still unknown; but there is no doubt that these ears permit the female locusts to hear the “songs” of the courting males. g.c., capsule of ganglion; nur.a. nucleus of attachment cell; nuc.s., nucleus of scolopale cell; nuc.f., nucleus of fibrous sheath-cell; nuc.Sc., nucleus of Schwann cell; scol., scolopale.

1871 "Primitive Culture" (Tylor, Sir Edward Burnett 1832–1917)

Proposed cultural evolutionism Culture (or civilization): integrated system of knowledge, belief (religion), art, ethic, law, custom, etc., obtained by the faculty of human who belong to the society

1931 "Science of Custom" (Benedict Ruth 1887-1948)

culture the is the univasal system of all the customs obtained by the members in the society, and is inherited socially

→ cultural anthropology
1946 "The Chrysanthemum and the Sword: Patterns of Japanese Culture (菊と刀)" (Benedict)
1949 "Male and female. A study of sexes in a changing world (女性と男性)" (Margaret Mead 1901-1978)

human development is depending on the cultural forms in belonging to the tribe and/or rations more than on the physical forms

human population - subsistence contrast
1949 "Social structure" (Murdock MG 1897-1985)

community: face to face association < band: nomadic
village: fixative, concentrared residential buildings, developing central parts
neighborhood: fixative, sporadic residential buildings, lacking coherence
