Mammalian intelligence depends mostly on the folds present in the cortex. The more folded the cortex the smarter. If you compare a rat brain to a human brain, the rats brain will be alot smoother and flatter.
Mammalian brains are extremely large compared to other animals. This makes it very easy to learn and gain the intelligence necessary to adapt and survive.
Neural tube
Neural Tube
They are called sulci (plural of sulcus).
The neural tube is the structure in mammalian embryos that develops into the brain and spinal cord. It forms from the ectoderm layer during development and gives rise to the central nervous system.
No, the limbic system is a set of brain structures involved in emotions, memory, and motivation, while the mammalian brain refers to the entire brain of mammals. The limbic system is a part of the mammalian brain.
helps increase the brain's surface area
The meandering ridges and valleys of brain coral give it the appearance of a mammalian brain.
The frontal lobe is considered a key brain structure in the measurement of human intelligence, as it is involved in functions such as problem-solving, decision-making, and complex thinking. Additionally, areas such as the parietal lobe, responsible for processing sensory information, and the hippocampus, involved in memory formation, also play significant roles in intelligence assessment. Ultimately, intelligence is a complex trait influenced by various brain regions working together.
Surface area.
Every part of the brain - except possibly the brain stem, where involuntary processes are - contributes to intelligence.
The blue whale has the largest brain of any animal, weighing around 15 pounds. However, in terms of complexity, the human brain is considered more advanced due to its structure and cognitive abilities.
