Neurons: The Axon01:21

Neurons: The Axon

7.3K
Axons are long, cytoplasmic processes of nerve cells capable of propagating electrical impulses known as action potentials. The cytoplasm or axoplasm of an axon contains neurofibrils, neurotubules, small vesicles, lysosomes, mitochondria, and various enzymes, all encased within the axolemma, the plasma membrane of the axon.
The axon attaches to the cell body at a cone-shaped elevation called the axon hillock. The initial part of the axon, closest to the hillock, is known as the initial segment....

Natural and Artificial Concepts

567
In psychology, concepts can be divided into two categories: natural and artificial. Natural concepts are formed through direct or indirect experiences. For example, consider the concept of snow. If you live in a place with regular snowfall, such as Essex Junction, Vermont, you know snow through direct experiences. You’ve seen it fall, touched it, shoveled it, and played in it. You recognize its texture, appearance, and even its smell. In contrast, if you live on an island like Saint...

Control System Problem01:21

Control System Problem

433
In an open-loop system, such as a basic thermostat, the poles of the transfer function influence the system's response but do not determine its stability. However, when feedback is introduced to form a closed-loop system, such as an advanced thermostat that adjusts heating based on room temperature, stability is governed by the new poles of the closed-loop transfer function.
When forming a closed-loop system, issues can arise if the poles cross into the unstable region, leading to potential...

Combinatorial Gene Control02:33

Combinatorial Gene Control

9.7K
Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

472
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Control Systems

1.9K
Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.
At the heart...

  • Biophysics
  • Neuroscience
  • Robotics

Background:

  • Artificial axons are synthetic assemblies mimicking nerve cell electrophysiology using lipid bilayers and ion channels.

Purpose of the Study:

  • To demonstrate the functional application of artificial axons as control elements in a robotic system.
  • To explore the potential of artificial nerve cell models in translating sensory input into behavioral output.

Main Methods:

  • Two artificial axons were employed as sensory input-dependent controllers.
  • The firing rate of the artificial axons was used as a control signal to steer a remote-controlled car.
  • The car's navigation towards a light source was analyzed from video recordings.

Main Results:

  • The artificial axons successfully controlled the direction of the remote-controlled car.
  • The car was steered towards the light source based on the sensory-dependent firing rates of the artificial axons.
  • This demonstrates a direct correlation between artificial neuronal activity and directed movement.

Conclusions:

  • Artificial axons can serve as functional control elements, bridging artificial electrophysiology and behavioral tasks.
  • This work supports a constructivist approach to understanding the relationship between nerve cell-level machine language and emergent behavior.
