Higher Mental Functions of Brain: Learning and Memory

Higher Mental Functions of Brain: Learning and Memory

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...

Radial System Protection

Radial System Protection

Radial systems employ time-delay overcurrent relays to reduce load interruptions. When a fault occurs, the nearest breaker opens first, while upstream breakers remain closed due to longer delay settings. This approach ensures minimal disruption to the rest of the system.
In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...

Muscles that Move the Arm

Muscles that Move the Arm

Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Assessment of radial pulse

Assessment of radial pulse

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

System of Memory

System of Memory

Memory is categorized into three major systems: sensory memory, short-term memory (STM), and long-term memory (LTM). These systems differ in their capacity and the duration for which they can hold information. Sensory memory captures raw sensory input from the environment, holding it for just a few seconds or less. For example, on hearing a brief, loud sound, like a car horn honking, the sound seems to linger in the mind for a moment even after it stops. This is an instance of sensory memory...

Working Memory

Working Memory

Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Background:

The radial arm maze (RAM) is crucial for studying spatial memory in animal models.
Existing RAM tools have limitations for human research and training.

Purpose of the Study:

To develop and validate a head-mounted-display RAM (HMD-RAM) program for human spatial learning and memory assessment.
To compare the efficacy of HMD-RAM with a traditional flat monitor setup.

Main Methods:

Forty participants completed virtual navigation tasks using either an HMD or a flat monitor.
Key metrics included working memory errors, reference memory errors, detection time, and head movements.
Program validity was confirmed through neuropsychological assessments and self-report measures.

Main Results:

HMD-RAM task results aligned with previous animal-based RAM studies.
The HMD resulted in greater presence, immersion, and simulator sickness compared to the flat monitor.
Creating environmental landmarks was identified as a key navigation strategy, enhanced by the HMD.

Conclusions:

The HMD-RAM is a valuable tool for assessing human spatial learning and memory.
It holds potential for the early diagnosis of spatial learning and memory deficits, such as those seen in mild cognitive impairment and Alzheimer's disease.
