This piece is dedicated to Anonymous and Jedi, Kak Teh, Anedra, Ely, Anne75, AuntyN & her hubby, Hogtied and Lady Jade. I found this from neuroskill.com.

If i play doctor i diagnose myself having brain injury at parietal and tempral lobes. Yamtuan, if you are reading this, dont la marah-marah anymore when i am forgetful and give you wrong directions. I am .. cough cough... not well. Highlighted in green is my 'observed problems'.

All the activities we perform each day, whether physical or mental, are directed by different parts of our brains. The brain has many parts including the cerebral cortex, brain stem, and cerebellum. Below is a list of functions and deficits or problems revealed when injury occurs at particular locations.

Frontal Lobe: Most anterior, right under the forehead.
How we know what we are doing within our environment (Consciousness).
How we initiate activity in response to our environment.
Judgments we make about what occurs in our daily activities.
Controls our emotional response.
Controls our expressive language.
Assigns meaning to the words we choose.
Involves word associations.
Memory for habits and motor activities.
Observed Problems:
Loss of simple movement of various body parts (Paralysis).
Inability to plan a sequence of complex movements needed to complete multi-stepped tasks, such as making coffee (Sequencing).
Loss of spontaneity in interacting with others.
Loss of flexibility in thinking.
Persistence of a single thought (Perseveration).
Inability to focus on task (Attending).
Mood changes (Emotionally Labile).
Changes in social behavior.
Changes in personality.
Difficulty with problem solving.
Inablility to express language (Broca's Aphasia).

Parietal Lobe: near the back and top of the head.
Location for visual attention.
Location for touch perception.
Goal directed voluntary movements.
Manipulation of objects.
Integration of different senses that allows for understanding a single concept.
Observed Problems:
Inability to attend to more than one object at a time.
Inability to name an object (Anomia).
Inability to locate the words for writing (Agraphia).
Problems with reading (Alexia).
Difficulty with drawing objects.
Difficulty in distinguishing left from right.
Difficulty with doing mathematics (Dyscalculia).
Lack of awareness of certain body parts and/or surrounding space (Apraxia) that leads to difficulties in self-care.
Inability to focus visual attention.
Difficulties with eye and hand coordination.

Occipital Lobes: Most posterior, at the back of the head.
Observed Problems:
Defects in vision (Visual Field Cuts).
Difficulty with locating objects in environment.
Difficulty with identifying colors (Color Agnosia).
Production of hallucinations
Visual illusions - inaccurately seeing objects.
Word blindness - inability to recognize words.
Difficulty in recognizing drawn objects.
Inability to recognize the movement of an object (Movement Agnosia).
Difficulties with reading and writing.

Temporal Lobes: Side of head above ears.
Hearing ability
Memory aquisition
Some visual perceptions
Catagorization of objects.
Observed Problems:
Difficulty in recognizing faces (Prosopagnosia).
Difficulty in understanding spoken words (Wernicke's Aphasia).
Disturbance with selective attention to what we see and hear.
Difficulty with identification of, and verbalization about objects.
Short-term memory loss.
Interference with long-term memory
Increased or decreased interest in sexual behavior.
Inability to catagorize objects (Catagorization).
Right lobe damage can cause persistant talking.
Increased aggressive behavior.

Deep in Brain, leads to spinal cord.
Heart Rate
Reflexes to seeing and hearing (Startle Response).
Controls sweating, blood pressure, digestion, temperature (Autonomic Nervous System).
Affects level of alertness.
Ability to sleep.
Sense of balance
Observed Problems:
Decreased vital capacity in breathing, important for speech.
Swallowing food and water (Dysphagia).
Difficulty with organization/perception of the environment.
Problems with balance and movement.
Dizziness and nausea (Vertigo).
Sleeping difficulties (Insomnia, sleep apnea).

Located at the base of the skull.
Coordination of voluntary movement
Balance and equilibrium
Some memory for reflex motor acts.
Observed Problems:
Loss of ability to coordinate fine movements.
Loss of ability to walk.
Inability to reach out and grab objects.
Dizziness (Vertigo).
Slurred Speech (Scanning Speech).
Inability to make rapid movements.
Obtaining a general understanding

Which part of the brain then controls the longing for somebody? Oh right.. that has nothing to do with the brain right? It's the heart. But if that has got nothing to do with the brain, then why is it that my mind always occupied with it? *sigh*

Ahh Ijun dear dear Ijun,
matters of the heart are always the trickiest for science to explain. You hang on in there! And chin up, always.
