Examples of feedforward processing in the following topics:
-
- The cerebellum differs from most other parts of the brain in that the signal processing is almost entirely feedforward—that is, signals move unidirectionally through the system from input to output, with very little recurrent internal transmission.
- This feedforward mode of operation means that the cerebellum, in contrast to the cerebral cortex, cannot generate self-sustaining patterns of neural activity.
- Signals enter the circuit, are processed by each stage in sequential order, and then leave.
- Thus, the cerebellar network receives a modest number of inputs, processes them very extensively through its rigorously structured internal network, and sends out the results via a very limited number of output cells.
-
- Cerebellar function was once believed to be motor-specific, but newer findings suggest the cerebellum is also involved in higher-level brain processing.
- Although a full understanding of cerebellar function has remained elusive, at least four principles have been identified as important: feedforward processing, divergence and convergence, modularity, and plasticity.
- Feedforward processing: The cerebellum differs from other parts of the brain (especially the cerebral cortex) in that the signal processing is almost entirely feedforward.
- This feedforward mode of operation means that the cerebellum, in contrast to the cerebral cortex, cannot generate self-sustaining patterns of neural activity.
- Signals enter the circuit, are processed by each stage in sequential order, and then leave.

- This feedforward mode of operation means that the cerebellum cannot generate self-sustaining patterns of neural activity, in contrast to the cerebral cortex.
- However, the cerebellum can receive information from the cerebral cortex and processes this information to send motor impulses to the skeletal muscle.
- Although a full understanding of cerebellar function remains elusive, at least four principles are identified as important: 1) feedforward processing, 2) divergence and convergence, 3) modularity, and 4) plasticity.
- Feedforward processing: Refers to the unidirectional
movement of signals through the system from input to output, with very little
recurrent internal transmission.
- Signals enter the circuit, are processed by each stage in sequential
order, and then leave.
-
- These alternative sensory responses from outside the digestive system are also known as feedforward reflexes.
-
- Serial memory processing compares a memory to a target stimulus, while parallel processing carries out multiple operations simultaneously.
- Serial memory processing is the act of attending to and processing one item at a time, while parallel memory processing is the act of attending to and processing all items simultaneously.
- Participants may process some serial memory sets using the self-terminating method and others with the exhaustive method.
- Parallel processing is the ability to carry out multiple operations or tasks simultaneously.
- In parallel processing, the brain simultaneously processes incoming stimuli of differing quality.
-
- The chemical reaction where ATP changes to ADP supplies energy for this metabolic process.
- For example, synthesizing glucose is an anabolic process, whereas the breaking down of glucose is a catabolic process.
- Each process has its own set of hormones that switch these processes on and off.
- Anabolic reactions constitute divergent processes.
- Bone mineralization and muscle mass are attributed to these processes.
-
- Four articular processes originate from the
joint between the pedicles and laminae, two point superiorly and two point
inferiorly.
- They interact with the zyhapophysis, a socket for the articular
processes, of the adjacent vertebrae to make the spine more stable and to facilitate a small degree of articulation.
- A single spinous process projects backwards
and downwards from the center of the vertebral arch and it serves as a major
attachment point for muscles and ligaments of the back.
- The two transverse processes project
laterally from the join between the pedicle and lamina and also serve as an
attachment point for muscles and ligaments of the back.
- The transverse processes articulate with the ribs in conjunction with the
vertebral body.
-
- Medical terminology is a language for accurately describing the human body and associated components, conditions, processes and process in a science-based manner.
- So, when a term is developed, some logical process is applied.
- Decoding the medical term is an important process.
- Once experience is gained in the process of forming and decoding medical terminology, the process begins to make sense and becomes easier.
- The process of learning a new language, such as medical terminology, is a challenging, yet attainable goal as the basic rules—once learned—make the process easier.
-
- Bone fractures are repaired through physiological processes in the periosteum via chrondroblasts and osteoblasts.
- While immobilization and surgery may facilitate healing, a fracture ultimately heals through physiological processes.
- The healing process is mainly determined by the periosteum (the connective tissue membrane covering the bone).
- These processes culminate in a new mass of heterogeneous tissue that is known as the fracture callus.
- The remodeling process continues with substitution of the trabecular bone with compact bone.
-
- Sensation and perception are two distinct stages of processing during human sensing.
- The
neural signals are transmitted to the brain and processed.
- The process of perceiving speech begins at the level of the sound within the auditory signal and the process of audition.
- After processing the initial auditory signal, speech sounds are further processed to extract acoustic cues and phonetic information.
- This speech information can then be used for higher-level language processes, such as word recognition.
