Sensor Area Inputs

• primary input - external world properties captured by sensor
• sensor control - origination of control data and nature of inter-area link - to be understood, see sections below
• perception feedback - time-based expectation for sensory data from perception area

Sensor Area Outputs

• primary output - sensory data, sent to perception area
• control feedback - providing status of control command execution - executed completely or partially, or somehow in different way
• exposed control state properties - emitted to external world to facilitate establishing direct communication channel with other subjects

Biological Eye Sensor Paths

• primary input
  • light -> rods (fast colorless contrast low-resolution receptors)
  • light -> cones (slow R/G/B high-resolution receptors)
• sensor control
  • prefrontal cortex/eye field -> BSA/superior colliculus -> BSA/horizontal gaze center
  • prefrontal cortex/eye field -> BSA/pretectum/horizontal gaze center
  • visual cortex/association cortex -> superior colliculus -> pretectum/horizontal gaze center
  • brain stem/midbrain/pretectum -> oculomotor, trochlear, abducent nerve (III, IV, VI cranial) -> pretectum/Edinger-Westphal nucleus -> ciliary ganglion -> eye

{code} constriction of pupil, accommodation of lens ciliary ganglion - parasympathetic ganglion Edinger-Westphal nucleus - parasympathetic cranial nerve nucleus {code}

• primary output
  • rods/cones -> thalamus/LGN/1-6 (main relay) -> primary visual cortex
  • rods/cones -> superior colliculus (10%, 150K axons - initiates move to orient eye toward stimulus - place it from peripheral field to fovea/macula)
  • rods/cones -> pretectum (pupil resize and accommodation reflex)
  • rods/cones -> hypothalamus (synchronize biological rhythms)

Linking Sensors to Perception - HLAv3

• sensor/data -> thalamus/input
• thalamus/output -> perception/feed-forward-input
• perception/feed-forward-output -> parietal/feed-forward-input
• perception/feed-back-output -> thalamus/input
• parietal/feed-forward-output -> sensor/control
• parietal/feed-back-output -> perception/feed-back-input
• sensor/feedback -> somatic/feed-forward-input
• somatic/feed-forward-output -> parietal/feed-forward-input
• somatic/feed-back-output -> parietal/feed-back-input

Linking Sensors to Perception

• for each sensor there is perception belief network for processing sensor data
  • several sensors are mapped to perception area
  • each sensor needs its own processing because of specific data format and patterns

Interesting facts

• when an animal attends to some features in its sensations, the neural representations even in the lowest cortical levels adapt mostly to those features and not to others
