Your cerebral cortex, also called gray matter, is your brain’s outermost layer of nerve cell tissue. It has a wrinkled appearance from its many folds and grooves. Your cerebral cortex plays a key role in memory, thinking, learning, reasoning, problem-solving, emotions, consciousness and functions related to your senses. Anatomy of the cerebral cortex. What is the cerebral cortex? Your cerebral cortex is the outermost layer of your Your cerebral cortex consists of six layers of nerve cells that contain between 14 billion and 16 billion nerve cells. It’s two millimeters (mm) to four mm (0.08 inches to 0.16 inches) thick. Your cortex is divided into four lobes: frontal, parietal, temporal and occipital. Each of these lobes is responsible for processing different types of information. Collectively, your cerebral cortex is responsible for the higher-level processes of the human brain, including language, memory, reasoning, thought, learning, decision-making, emotion, intelligence and personality. Why is the cerebral cortex called gray matter? The gray matter found in the outer layer of your brain consists of nerve cell bodies, including the end portion of nerves called dendrites. Dendrites are the part of a nerve cell that receives the chemical message from another cell. Your cerebral cortex is gray because that section of the nerve lacks the fatty covering material called myelin. White matter in your brain is made up of bundles of axons, the long center section of a nerve cell...

Research estimates that short-term memories only last for about 30 seconds. When you read a line in a book or a string of numbers that you have to recall, that’s your short-term memory at work. You can keep information in your short-term memory by rehearsing the information. For example, if you need to recall a string of numbers, you might keep repeating them to yourself until you input them. However, if you are asked to recall those numbers about 10 minutes after inputting them, you’d most likely be unable to. Explicit long-term memories are memories we consciously and deliberately took time to form and recall. Explicit memory holds information such as your best friend’s birthday or your phone number. It often includes major milestones in your life, such as childhood events, graduation dates, or academic work you learned in school. • Episodic memories are formed from particular episodes in your life. Examples of episodic memory include the first time you rode a bike or your first day at school. • Semantic memories are general facts and bits of information you absorbed over the years. For instance, when you recall a random fact while filling in a crossword puzzle, you pull it from your semantic memory. Why Do We Have Different Types of Memory? Each different type of memory we have is important, and they all have various functions. Your short-term memory allows you to process and understand the information in an instant. When you read a paragraph in a book and understand it...

The term "short-term memory" is often used interchangeably with "working memory," which refers to the processes that are used to temporarily store, organize, and manipulate information. In a famous paper published in 1956, psychologist George Miller suggested that the capacity of short-term memory for storing a list of items was somewhere between five and nine. Some memory researchers now believe that the true capacity of short-term memory is probably closer to four. Research has shown that one of the critical factors that influence memory failure is time. Information is often quickly forgotten, particularly if people do not actively review and rehearse the information. Sometimes information is simply lost from memory and, in other cases, it was never stored correctly in the first place. Some memories compete with one another, making it difficult to remember certain information. In other instances, people actively • Write it down: The act of writing with a pen and paper helps implant the memory into your brain—and can also serve as a reminder or reference later on. • Attach meaning to it: You can remember something more easily if you attach meaning to it. For instance, if you associate a person you just meet with someone you already know, you may be able to remember their name better. • Repeat it: Repetition helps the memory become encodedbeyond your short-term memory. • Group it: Information that is categorized becomes easier to remember and recall. • Test yourself: While...

The GPU or Graphics Processing Unit is specialized to crunch numbers efficiently to output smooth graphics from something like a video game. The CPU can basically do anything but since the architecture of the GPU is more efficient for rendering graphics it hands the workload to the GPU. Both are types of microprocessers that handle different tasks. The GPU is generally divided up into many cores whereas the CPU is only split into a few cores. GPUs are also used for mining cryptocurrencies since they can crunch numbers so quickly. Hope this helps. Can the CPU actually store data? My very generic google surch tells me it stores only the data necessary forr the current operation, but that seems awfully close to the description of the RAM-Memory in the following class. So the CPU only processes it and stores it in RAM-Memory or does the CPU store the data too? Hey guys, I'm really curios to know how the control unit - which knows how to interpret program instructions - and the Arithmetic Logic Unit (ALU), which knows how to add the numbers in this lessons diagram, work? Like how does the circuitry in the CPU know how to execute these instructions? Thanks! What is the special memory used only by the CPU? A: Registers (collectively referred to as L1 Cache) Where is it located? A: On the chip, next to the ALU What are the different types of this special memory? A: Types of registers included will vary by processor, but usually some combination of - Acumulator (ACC): stores data f...
