 | | The anterior intermediate area is concerned in the coodinations of those nerve impulses which are concerned with the relationships of the individual to his environment. | | | Thus, the area between the visual and the somesthetic overflows is concerned in the appreciation of ideas resting upon the proper correlation of the primary sensations of sight, touch, and the sensations associated with simple muscular efforts. | | | The daily variations of obstinacy and pliability depend in such persons upon the variations in the physiological conditions of the neuron systems concerned in the relationships of the motor areas, the sensory and intermediate areas, and the different ganglionar centers in which the instinctive and emotional reactions are coordinated. |

| | How Brains Are Put Together |
| | Most of the primary sensory cortices (visual, auditory and somatosensory) receive their main input from a region in the brain called the thalamus, which is itself divided in specific regions and connected to the eyes, the ears and the skin. | | | As we have already indicated, the cortex is important for the representation of sensory stimuli and the control of motor behavior. | | | These areas turned out to correspond quite well to areas that have come to be functionally defined by electrophysiology. |

| | The higher domains of the cortex itself are using the primary sensory holoprojections to derive associational information such as that concerning depth perception, for example (from both audio and visual sources in combination), as well as perception of motion, types and categories of perceptions, as well as cross-modal associations. | | | This brain area, it will be remembered, has been suggested both in the literature and in my own model as an important center involved with the working memory and with the most complex levels of associative processing by the cortex. | | | In addition, it is found that nearly all of the connections are two-way, the connections between the thalamus and the primary sensory areas of the cortex, for example, being reciprocated by nerve pathways (backprojections) in the opposite direction. |

| | Perception, imagery, and the sensorimotor loop |
| | While it may perhaps be maintained that pure sensory qualia (whatever those might be) have a modality-specific character (sounds are unlike colors), there are clear commonalities between characteristics of visual, kinaesthetic, and auditory perceptual experience; and more interesting still there are commonalities between these modes of perceptual experience and behavioral skill. | | | As a result of this unification, the executive centers are not in the business of trying to manipulate the character of sensory experience, but are rather in the business of trying to manipulate entities in the environment. | | | Moreover, if practicing a motor behavior generally facilitates more skilled performance by improving the efficiency of the executive motor areas, and if during imagery those same centers are receive feedback similar to the feedback they would be getting with overt practice, then imagined practice should also increase motor skills. |

| | Tactile and olfactory adjectives were chosen because the primary and secondary processing areas associated with these senses are fairly distant from the areas involved in the input processing of auditory and visual word stimuli. | | | One question, though, is whether this evidence supports a crucial role for primary sensory areas in on-line word meaning comprehension, or whether it merely shows that these areas become active at sometime after a sensory adjective is encountered. | | | The long-term goal of this investigation is to provide compelling data that bear on current theories about the relationship between lower-level brain systems (and perceptual-cognitive constructs), and higher-level "associative" brain systems (and cognitive constructs). |

| | 2.01: NERUOSCIENCE -- Vision |
| | One hypothesis is that only the most highly integrative, cognitive set determining brain areas (typically frontal) are responsible for generating this inherently reflexive, self referential state of controllable awareness, while primary sensory areas and lower level integrative areas merely contain passive maps or representations of external conditions accessible to the senses. | | | While the relevant primary sensory area was the least affected by these attentional changes, both for primary auditory and visual cortex significant modulation was observed. | | | Thus the experimental evidence suggests that it is inappropriate to draw sharp distinctions between brain areas responsible and not responsible for supporting the experience of consciousness. |
