Lateral prefrontal cortex

Lateral prefrontal cortex is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lateral prefrontal cortex rather than just read about it. In short: In human brain anatomy, the lateral prefrontal cortex (LPFC) is part of the prefrontal cortex (PFC). According to Striedter the PFC of humans can be delineated into two functionally, morphologically, and evolutionarily different regions: the ventromedial PFC (vmPFC) present in all mammals and the LPFC present only in primates.

Key takeaways

Lateral prefrontal cortex belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Lateral prefrontal cortex to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lateral prefrontal cortex from memory before moving on to harder problems.

Reference excerpt

In human brain anatomy, the lateral prefrontal cortex (LPFC) is part of the prefrontal cortex (PFC). According to Striedter the PFC of humans can be delineated into two functionally, morphologically, and evolutionarily different regions: the ventromedial PFC (vmPFC) present in all mammals and the LPFC present only in primates. The LPFC contains the Brodmann areas BA8, BA9, BA10, BA45, BA46, and BA47. Some researchers also include BA44. The LPFC is often further divided into dorsolateral prefrontal cortex (BA8, BA9, BA10, BA46) and ventrolateral prefrontal cortex (BA45, BA47, BA44).

Function The LPFC is primarily involved in working memory, reasoning, planning, and active forms of imagination: Prefrontal Synthesis, mental rotation, and integration of modifiers. The other part of the PFC, called the Ventromedial prefrontal cortex, is primarily concerned with inhibition of urges, motivation, identification of rewarding or otherwise significant stimuli, as well as mood and empathy.

Worked examples

Example 1 — a first encounter with Lateral prefrontal cortex

Start with the simplest possible case. Write down what Lateral prefrontal cortex claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lateral prefrontal cortex before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lateral prefrontal cortex ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lateral prefrontal cortex

In research: Lateral prefrontal cortex appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lateral prefrontal cortex in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lateral prefrontal cortex is common in secondary-school and first-year university syllabi. It links to neighbouring topics Neurology, so understanding it makes those chapters shorter.
In everyday life: Look for Lateral prefrontal cortex outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Lateral prefrontal cortex in simple terms?

Why does Lateral prefrontal cortex matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Lateral prefrontal cortex?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
