Brain Waves01:23

Brain Waves

1.7K
Brain waves are electrical signals generated by the neurons in the brain, which are regularly monitored to measure mental activities. Brain waves and their frequency ranges can be measured using an electroencephalogram or EEG. There are four main types of brain waves, each with distinct characteristics:

Higher Mental Functions of Brain: Learning and Memory01:26

Higher Mental Functions of Brain: Learning and Memory

913
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

Storage01:23

Storage

113
A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze...

Overview of Synapses01:25

Overview of Synapses

2.4K
A synapse is a specialized structure where two neurons connect, allowing them to pass an electrical or chemical signal to another neuron. It is the point of communication between neurons. The term "synapse" is derived from the Greek word "synapsis," which means "conjunction." The entire process of neural communication revolves around the synapse. When activated, a neuron releases chemicals known as neurotransmitters into the synapse. These neurotransmitters cross the synapse and bind to...

Stages of Sleep01:22

Stages of Sleep

406
Sleep progresses through distinct stages, each characterized by specific brain wave patterns and physiological responses ranging from wakefulness to stages of non-rapid eye movement, known as non-REM, to rapid eye movement, referred to as REM. Understanding these stages helps in recognizing how sleep supports various bodily and cognitive functions.
Before sleep begins, in wakefulness, the brain exhibits primarily beta waves, which are high in frequency and low in amplitude, indicating alertness...

Understanding Memory01:19

Understanding Memory

570
Memory is the retention of information or experiences over time, facilitated through three main processes: encoding, storage, and retrieval. Encoding is the process of inputting information into the memory system. For instance, when listening to a lecture, watching a play, reading a book, or having a conversation, the brain is actively encoding information. This initial stage involves transforming sensory input into a form that can be processed and stored by the brain. Various factors, such as...

Area of Science:

  • Neuroscience
  • Computational Neuroscience
  • Artificial Intelligence

Background:

  • Current understanding of brain function lacks a physical theory for internal electrical signal communication.
  • Existing Artificial, Recurrent, Convolution, Spiking Neural Networks (ARCSe NNs) are based on simplified neuronal integration and firing models.
  • This limits the development of advanced Artificial Intelligence (AI) and Machine Learning (ML) methods.

Purpose of the Study:

  • To propose a novel physical model for brain communication based on weakly evanescent brain wave propagation (WETCOW).
  • To investigate the learning and memory capabilities of the WETCOW framework.
  • To apply the WETCOW model to AI/ML and neural network applications.

Main Methods:

  • Developed a physical model of weakly evanescent brain wave propagation (WETCOW).
  • Hypothesized that neurons synchronize/desynchronize guided by nonlinear near-critical brain waves.
  • Applied the WETCOW framework to AI/ML tasks and compared performance with deep ARCSe NNs.

Main Results:

  • Demonstrated that WETCOW framework supports efficient coherent synchronization/desynchronization of neurons.
  • Showcased learning and memory capabilities within the WETCOW framework.
  • WETCOW-inspired learning achieved superior timing and accuracy over deep ARCSe counterparts on standard datasets, despite being shallow.

Conclusions:

  • The WETCOW model provides a new physical basis for understanding brain communication, learning, and memory.
  • Nonlinear, near-critical brain waves, previously considered noise, play a crucial role in sophisticated neural processing.
  • This framework offers a promising alternative for developing more efficient and accurate AI/ML algorithms.
