Uncovering the Mystery of the Human Brain with Computational Neuroscience

Image
Uncovering the Mystery of the Human Brain with Computational Neuroscience The human brain is a complex and unfathomable supercomputer. How it works is one of the ultimate mysteries of our time. Scientists working in the exciting field of computational neuroscience seek to unravel this mystery and, in the process, help solve problems in diverse research fields, from Artificial Intelligence (AI) to psychi atry . Computational neuroscience is a highly interdisciplinary and thriving branch of neuroscience that uses computational simulations and mathematical models to develop our understanding of the brain. Here we look at: what computational neuroscience is, how it has grown over the last thirty years, what its applications are, and where it is going. The evolution of computational neuroscience The term Computational Neuroscience was first coined by Eric L. Schwartz at a conference held in 1985. The first graduate program titled the ‘Computational and Neural Systems (CNS) PhD Program’ was ...

New research highlights the alarming impact of sleep deprivation on cognitive function

New research highlights the alarming impact of sleep deprivation on cognitive function A recent study published in Experimental Brain Research has shed new light on how total sleep deprivation impacts the brain’s ability to process and integrate multiple stimuli presented in quick succession. The researchers found that a complete day without sleep significantly impairs both attentional and temporal integration mechanisms. In other words, going without sleep for a whole day seriously hinders our ability to pay attention and process information quickly, which is crucial for reacting correctly to fast changes around us. Humans have a limited ability to process several events when they occur simultaneously or in quick succession. This limitation is evident in a phenomenon known as the attentional blink. The attentional blink is the difficulty people have in identifying the second of two stimuli presented closely together in time. The study aimed to explore how total sleep deprivation affe...

Introverted Sensing in cognitive sensing

Image
 Introverted Sensing (Si) is one of the cognitive functions identified in Carl Jung's theory of psychological types, which forms the basis of the Myers-Briggs Type Indicator (MBTI). Si is primarily concerned with internal sensations and experiences and is associated with the following characteristics: Key Characteristics of Introverted Sensing (Si) Detail-Oriented Memory : People with dominant Si often have a keen memory for details and past experiences. They can recall specific information, such as dates, facts, and personal experiences, with great accuracy. Focus on the Past : Si users are often oriented towards the past. They draw on previous experiences and established methods to guide their present actions and decisions. Preference for Routine : Those who favor Si typically enjoy routines and familiar environments. They feel comfortable and secure when following established patterns and processes. Attention to Physical Sensations : Si involves a heightened awarene...

Four principles of cognitive development >>>

Image
The four principles of cognitive development, often discussed in the context of Jean Piaget's theory, include:  Sensorimotor Stage (Birth to 2 years):   Characteristics: In this stage, infants learn about the world through their senses and actions. They develop object permanence, realizing that objects continue to exist even when they cannot be seen or heard. Developmental Milestones: Sucking, grasping, looking, and listening; developing schemas; beginning of goal-directed actions. Preoperational Stage (2 to 7 years): Characteristics: Children begin to use language to explore and understand their worlds. They are egocentric, meaning they have difficulty seeing things from perspectives other than their own. Developmental Milestones: Symbolic thinking, use of proper syntax and grammar, imagination and intuition strong, but complex abstract thought still difficult. Concrete Operational Stage (7 to 11 years): Characteristics: Children start to think logically about concrete...

Cognitive science in Natural language processing >>>

Image
Cognitive science plays a crucial role in shaping and advancing the field of Natural Language Processing (NLP). It encompasses the interdisciplinary study of the mind and its processes, including perception, thinking, learning, and language. Here's how cognitive science informs and intersects with NLP: 1. Understanding Human Language Processing: Cognitive science provides insights into how humans process language, which in turn guides the development of NLP models. Understanding aspects like syntax, semantics, and pragmatics from a cognitive perspective helps in building systems that can better mimic human language understanding and generation. 2. Language Acquisition and Learning: Studies on how children acquire language inform the algorithms and learning methods used in NLP. For instance, concepts such as incremental learning, exposure to varied language inputs, and the critical periods of language learning influence the design of training regimes for language models. 3. Mental...

Neural networks and brain imaging techniques

Image
Neural networks and brain imaging techniques Neural networks and brain imaging techniques are at the forefront of cutting-edge research in neuroscience and technology, and recent advancements in these areas have made significant impacts. Neural Networks and Brain Mapping: Researchers are utilizing advanced techniques like synchrotron X-ray tomography and volume electron microscopy to create detailed maps of brain structures. This allows scientists to visualize entire neural networks and specific cellular structures at nanometer resolution. The approach combines data from multiple imaging methods to produce comprehensive maps, which are valuable for studying neural circuits in mammals and potentially other tissues like cancer cells​  AI and Imaging Optimization : Artificial intelligence (AI) is revolutionizing the speed and efficiency of brain imaging. For instance, the SmartEM system leverages machine learning to expedite electron microscopy imaging, reducing the time required fo...
